Abstract

PURPOSE:To facilitate display of an hour angle data of the moon by computing the hour angle data of the moon at specified position and time from at least from time information of year, month, day and hour units and positional information on the earth. CONSTITUTION:Time stored into a register subjected to a time counting processing is converted into Greenwich mean time. Based on a variable T (quotient of number of days elapsed from noon of Jan. 1, 2,000 (UT time) divided by 36,525 days), Greenwich sidereal time and an apparent right ascension of the moon at UT=zero o'clock are determined to calculate an hour angle of the moon from the results. Then, the hour angle of the moon is determined at UT=zero o'clock in the following morning to obtain a cycle of lunar day. Time when the hour angle of the moon reaches noon is calculated. Then, time (t) when the hour angle of the moon reaches noon at an optional point is determined to calculate the hour angle of the moon is calculated at time t' specified. A hour angle of the moon at both times (t) and t' is determined by a proportional calculation from a difference between the times and the results are subtracted from a hour angle 0h (24 o'clock) of the moon to determine the hour angle of the moon at the time t'. In other words, an hour angle of the moon can be obtained at arbitrary time from a longitude at an optional point.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a lunar data display device that can accurately display the hour angle of the moon and the like.

[Prior art and its problems]

Conventionally, as a device for displaying lunar data, a lunar phase (or lunar fe?f) display board that displays the moon phase is provided on the dial of an analog clock, and the phases of the moon can be determined by rotating the moon phase display board. A display is being considered. These devices can, for example,
The moon phase display board rotates once every 9.5 days to display the moon phase at that date and time.

In addition to the above-mentioned lunar movement that has a cycle of approximately one month, the moon's movement includes diurnal movement, which is the movement of the moon on -day, and the position of the moon on the celestial sphere at this time is There is an hour angle of the moon. The hour angle of the moon refers to the angle between the hour passing through the moon and the meridian.The hour angle when the moon is midline with the meridian (south center in the Northern Hemisphere) is the hour angle between the meridian and the moon. The westward angle (0" to 360') made by the moon is expressed from 0 o'clock to 23 o'clock. For example, if the hour angle of the moon is 6 o'clock, 15" x 6 = 90 degrees, and from south to west This means that the moon can be seen at 90 degrees in the direction, or due west.

It has been said for a long time that the above-mentioned moon movement and diurnal movement affect the feeding activities of animals. 1
It is empirically known that times such as 2 o'clock and 18 o'clock are suitable for fishing and hunting.

Therefore, it would be extremely convenient to know the moon's phase and hour angle when fishing, hunting, etc. However, there is currently no device that can easily determine the moon's hour angle data. First, if you wanted to know the moon's hour angle data, you had to go to a specialized facility that had astronomical data to find out, and it was not easy to find out the moon's hour angle data.

(Object of the Invention) An object of the present invention is to provide a lunar data display device that allows lunar hour angle data to be known extremely easily.

[Key points of the invention]

The present invention calculates the hour angle data of the moon at a specified position and time from at least time information in year, month, day, and hour units and position information on the earth, and calculates the time of the moon obtained by the calculation. It displays angle data, allowing you to easily know when is the best time for fishing, hunting, etc.

Next, the operation of the embodiment configured as above will be explained.

FIG. 5 is a flowchart illustrating the overall processing content of the embodiment.

The system typically performs the Holt (HA) step S1 in FIG.
LT) state, and executes the time measurement process in step S2 in units of minutes or less, for example, every 16 Hz. In this sub-minute time counting process, time is measured in units of 1716 seconds, seconds, and minutes, and a time carry signal is output when the minute reaches 60 minutes. Then, in the next step S3, it is determined whether or not there is a time carry signal. When the time carry signal is generated, the flag F0 is set to "1" (S4). The reason why the flag Ft is set to "1" is to perform the hour angle calculation of the moon, which will be described later, in units of one hour.

Thereafter, the hourly time measurement process of step S5 is executed. In this hour unit time measurement process, as a result of the minute time measurement process (S2),
If an hour carry signal is generated, 1 is added to the hourly data, and when the added time exceeds 24 o'clock, a day carry signal is further output.

Thereafter, in step S6, it is determined whether or not there is a day carry signal. When the day carry signal is generated, the flag F+
is set to "1" (S7).

The reason why the flag Fo is set to "l" is to perform the moon phase calculation, which will be described later, with emphasis on one bite.

Then, in the next step S8, day, month, day of the week, and year time counting processing is executed. In this day, month, day of the week, and year timekeeping process, if a day carry signal is generated, the day of the week is changed and 1 is added to the daily data. If the addition results in monthly or yearly carry,
Furthermore, the time data is updated on a monthly and yearly basis, and the updated time data is transferred to the time register X of the RAM 9.

When the time counting process is completed as described above, the process proceeds to step S9, and it is determined whether or not the flag Fo is set. If F,=O, that is, if the hour carry signal is not generated, the process advances to step 316, where the current time data stored in the register X is displayed on the display section 2.

On the other hand, if F0=1, it is the calculation timing to calculate the hourly lunar hour angle, and the lunar hour angle calculation process in step S10 is executed.

The lunar hour angle calculation process in step 310 will be explained in detail with reference to the flowchart of FIG.

In step S21 of FIG. 6, first, the time stored in register Store in register Zo.

Then, in the next step S22, a variable T for determining the visible right ascension of the moon when Griezzi is fixed is calculated and stored in the register Z of the RAM 9.

Here, the variable T is the number of days that have passed since 0:00 on January 1, 2000 (Greenwich time: GMT = UT time) divided by the Nilus century (36525 days), year = YE, month = MN. , day = DA, hour unit = HO, W = (YE-1900) /4 F = FRAC (W) A = I NT (1461XW) B = INT ((MN + 7) / 10) C = TNT (1 -F) D= I NT (0,44X (MN+ 4.4
)) Z=A+31 xMN+DA+ (B -1)x
When C-BXD+HO/24, the variable T can be expressed by the following formula.

T = (Z -36556,5) /36525 A variable T is calculated from this formula, and the calculated value is stored in register Z1 of RAM9.

Next, in step S23, the Griezzi sidereal time at UT=O is determined.

When Y = Z-25012, when it is a Grieczi star, it can be expressed by the following formula.

K=24XFRAC(0,0027379XY)
The Griezzi sidereal time is calculated from the above formula, and the calculated value is stored in the register Z2 of the RAM 9.

Next, in step S24, the visible right ascension of the moon at UT=O is calculated.

α=32084.52539 x T + 14.55441 +0.41925 x COS (477198,86
8x T +44°+0.16358 x COS

700), the visual right ascension of the moon: α(m) is expressed as ex(m)=24xFRAC(α/24).

The visual right ascension of the moon at UT-0 is calculated from the above formula, and the value is stored in register Z3 of RAM9.

Next, in step S25, from the Grietsgi sidereal time and the moon's apparent right ascension obtained as described above, U at Greenwich is
Calculate the hour angle of the moon at T=O time.

Moon's hour angle: JK can be calculated from the following formula.

K: Sidereal time, α(m) Niga's visual right ascension.The hour angle of the moon obtained from the above formula is stored in register Z4 of RAM9.
Store in.

Since the hour angle of the moon at UT=O in Greenwich on that day has been obtained as described above, the next day's hour angle is calculated.

First, in step 326, the date data of the time stored in register Z1 is incremented by 1 and stored in register Zn, and in the same way as in step S22, the variable T for the next day that has been incremented by 1 is calculated and stored in register Z of RAM9. do.

Next, in steps 328 and 29, steps 323 and 29 are performed, respectively.
In the same manner as in S24, calculate Grietzgi sidereal time and the moon's visual right ascension at 0UT=O the next day, and use these values as RA.
Store in registers Z6 and Z7 of M9.

Then, in the next step S29, the hour angle of the moon at UT=0 in Greenwich on the next day is determined from the Griezzi sidereal time of the next day and the visible right ascension of the moon, and the value is stored in the register ZII of the RAM 9.

Since the hour angle of the moon on the current day at UT=0 in Greenwich and the hour angle of the moon on the next day have been determined by the above calculation, the lunar diurnal cycle of the moon is then calculated in step S30.

The lunar diurnal cycle is the time from when the moon's hour angle becomes Oh until the next time when the moon's hour angle becomes oh, and indicates the time of one cycle of the moon's diurnal movement.

Then, the lunar diurnal cycle: LNR can be expressed by the following formula.

LNR= Calculate the lunar cycle from the above formula and store the value in register Z9 of RAM9.

FIG. 7 is a chart showing an example of calculation of the lunar diurnal cycle.

For example, the hour angle of the moon at UT=O in Greenwich is 3
．． 8h, and the hour angle of the moon at 0UT=O the next day is 3°1h, then DJK=3.1h-3,8h=-0.7h.

Therefore, the lunar diurnal cycle: LNR can be determined as follows: LNR=576/(-0,7+24)=24.7h.

Returning to FIG. 6, in the next step S31, the time (UT time) when the moon's hour angle becomes 0 o'clock is calculated.

The time when the hour angle is 0 o'clock can be expressed by the following formula.

The time at which the hour angle of the moon becomes 0 o'clock in Greenwich is determined from the above equation, and the value is stored in the register ZIO of the RAM 9.

FIG. 8 is a chart showing an example of calculation at UT when the hour angle is 0 o'clock.

For example, if the hour angle of the moon at UT=O is 3.8 h, the time when the hour angle = oh is (24-3 ,8) x (24,7/24) =20
．． It can be calculated as 79:00 (20:47).

Returning to FIG. 6, from the time when the hour angle of the moon in Greenwich obtained by the above-mentioned calculation becomes 0 o'clock, the next step S32
Then, calculate the time when the moon's hour angle becomes 0 o'clock at the point being measured or at the specified point.

The time t at which the moon's hour angle becomes 0 o'clock at any point can be found using the following formula.

Substitute the longitude of the point being measured or specified and the time difference from Greenwich into the above equation, find the time when the moon's hour angle becomes 0 o'clock at that point, and store that time in register Z1 of RAM9.
Store in 1.

For example, the time when the moon's hour angle is 0 o'clock in Tokyo at 139.75° east longitude is the time difference between Tokyo and Greenwich (+9
time) and the lunar diurnal cycle (2
4,7 o'clock), UT time when hour angle = 0 o'clock (20,79 o'clock)
becomes as follows.

t = 20.79 o'clock + 9 o'clock = 20.20 o'clock = 20:12 If the time at which the hour angle of the moon becomes 0 o'clock at any point is found by the above calculation, then in step S33 the current time being measured is determined. Alternatively, the hour angle of the month at the specified time is calculated and stored in register G of the RAM 9.

FIG. 9 is a chart showing an example of calculating the hour angle of the moon at 11:35 in Tokyo.

The lunar diurnal cycle calculated by the above calculation = 24.7 hours,
The time difference (8,6
2 o'clock), the lunar hour angle difference at both times can be determined by proportional calculation.

When calculating the hour angle difference by proportional calculation, the hour angle difference = 24
8.62÷24.7=8.38 h. If we subtract this hour angle difference from the moon's hour angle 0h (=24h), we get 11
The moon's hour angle at 35 minutes can be calculated as 15.62h.

That is, by specifying the longitude of an arbitrary point and the time difference from Greenwich, the hour angle of the moon at that point at an arbitrary time can be easily determined by the above-mentioned calculation.

After completing the moon hour angle calculation in this way, the fifth
At step Sll in the figure, the flag F0 is reset to "0". Then, in the next step S12, it is determined whether the flag F1-1 is set.

When the flag F1=1, that is, when 24 hours have passed and the date has changed, the process advances to step S13 and a moon phase calculation is executed.

FIG. 10 is a detailed flowchart of the moon phase calculation in step S13.

First, in step 341, the time stored in the current time register X is converted to Greenwich time based on the time difference from Greenwich stored in register B.

Thereafter, in step 342, the aforementioned variable T is calculated from the Greenwich time.

Next, in step S43, the ecliptic longitude of the moon is calculated from the variable T obtained in step S42 using the following formula.

Moon's visual longitude = 481267.9 x T + 218
．． 3+6.3XCO3 (45+4572000 XT)
Similarly to +1.3XCO3 (11+413300XT),
In the next step S44, the ecliptic longitude of the sun is calculated from the variable T using the following formula.

Sun's visual longitude -36000,8X T +280.5+
1.9x COS (26B +36000 x T
) The elongation of the moon is determined in the next step 345 from the difference between the ecliptic longitude of the moon and the ecliptic longitude of the sun calculated as described above. The lunar elongation is the angle between the sun and the moon as seen from the Earth, and changes in this elongation change the moon's phase. for example,
When the elongation is 0°, it is a new moon, when the elongation is 180°, it is a full moon, and when the elongation is 270°, it is a waning moon.

Next, in step S46, the lunar age is calculated from the lunar elongation and the period of the lunar month. In this embodiment, the period of the moon's lunar month is an average of 29.53 days, and the age of the moon at Greenwich time is calculated by proportional calculation from the period and the elongation of the moon calculated each day. The time difference between that point and Greenwich is then used to determine the age of the moon at that point.

That is, the age of the moon at any point can be expressed by the following formula.

FIG. 16 is a chart illustrating the relationship between the moon phase, the elongation of the moon, and the moon age determined by the moon age calculation described above.

If the difference between the ecliptic longitude of the moon and the ecliptic longitude of the sun calculated by the above calculation (moon elongation) is in the range of 0° to 22.5°, for example, the lunar age is 0 depending on the elongation. The value will be any value in the range of .0 to 1.8 days, and the moon age data obtained at this time will be stored in RAM.
Write to register E of 9. A moon age of 0.0 to 1.8 days corresponds to a new moon.

Similarly, if the elongation of the moon is, for example, 157.5” to 202.5
If it is in the @ range, the age of the moon is 1 depending on the elongation at that time.
The value will be any value in the range of 3.0 to 16.6 days, and the moon age determined at this time will be written in the register. Monthly age 13.0~
16.6 corresponds to a full moon.

The same applies when the elongation is in other angular ranges, and the relationship between the elongation, the moon age, and the moon phase calculated by calculation is the 16th angle.
As shown in the diagram in fig.

Returning to FIG. 5, if the moon phase calculation is completed, step 514
, and reset the data flag F1 to O.

After the completion of step 314, or when flag F=0 in the determination of step S12, step 3
Proceed to step 15 to execute a phishing operation.

Phishing calculation is to obtain feeding activity data indicating the feeding activity of animals from the moon phase and hour angle of the moon, judge whether the current time is suitable for fishing and hunting, and indicate whether or not it is suitable for fishing or hunting. This is a calculation for displaying by the four fish mark display bodies 2f.

FIG. 11 is a flowchart showing the contents of the phishing calculation in step S15.

First, in step STI, moon phase data corresponding to the moon age obtained by the above-mentioned moon age calculation is obtained, and further, the moon phase data and the current time at the point during time measurement obtained by the above-mentioned lunar hour angle calculation are obtained. The fish mark number data to be displayed is obtained from the moon hour angle data and stored in one of the registers Z.

Then, in the next step ST2, the numerical value obtained in the above step STI is stored in a register N in the RAM 9 that stores the number of displayed fish marks. For example, if the current time is the most suitable time for fishing and hunting, a value "4" is written in the register N, and if the current time is the second most suitable time, a value "3" is written in the register N.

FIG. 17 shows the result of the above-mentioned phishing operation on the display section 2.
2 is a chart showing the relationship between the number of fish marks displayed on the screen and the moon phase and hour angle of the moon.

For example, when it is a new moon or a full moon and the moon's hour angle is 0 o'clock or 12 o'clock, it is the most suitable time for fishing and hunting, and the value obtained by step STI calculation is "4", and step ST2 “4” is written to register N. As a result, four fish marks are displayed on the display section 2 by the display process of step 316 in FIG. 5, which will be described later.

Also, when the moon's hour angle is 6 o'clock or 18 o'clock with a new moon or full moon, or when the moon's hour angle is 0 o'clock or 12 o'clock with a waxing or waning moon.
The hour is the second most suitable time for fishing and hunting, and when the moon phase and hour angle of the moon match the above conditions, "3" is written in register N. As a result, three fish marks are displayed on the display section 2.

Furthermore, if it is a new moon or a full moon, the hour angle of the moon is 0 o'clock, 12 o'clock, or 6 o'clock.
If it is a time other than 6 p.m., it is the third most suitable time for fishing and hunting, and "2." is written in register N.
Two fish marks are displayed on the display section 2.

Similarly, as shown in Figure 17, the number of fish marks is determined based on the moon phase and hour angle of the moon at that time, and the number of fish marks determines whether the time is suitable for fishing and hunting. Is displayed.

Therefore, from the number of displayed fish marks, it is possible to easily know the suitable time for fishing and hunting during time measurement (or at a designated point).

Returning to FIG. 5, once the phishing calculation in step S15 is completed, display processing in step S16 is then executed. In this display process, various data obtained by the above-described time measurement process, lunar hour angle calculation, lunar age calculation, and phishing calculation are displayed.

The contents of the display process in step S16 will be explained in detail with reference to the flowchart of FIG.

First, in step S51, it is determined whether the value of the mode register M is O. If the time display mode is M=O,
In the next step S52, the time data stored in the current time register X is transferred to the display register A4.

Furthermore, in the next step 353, moon phase data to be displayed is calculated from the moon age data stored in register E and stored in display register A1.

In this embodiment, the moon phase is displayed in nine stages, and it is determined from the moon age data which of the nine stages the moon phase corresponds to, and the corresponding moon phase indicator 2a is designated "1 to 9". The numerical data is written to display register A+ as moon phase data. For example, when the moon phase data is in the range of 0.0 to 1.8 days, the value "1" is set in the display register A1 in order to light up the first moon phase indicator 2a+ representing the new moon.
”.

In the next step 354, from the hour angle data stored in the register G, the hour angle display 2 of the display section 2 from 0 to 23 o'clock
Data specifying either one of c is written to display register A2.

For example, if the hour angle of the month stored in the register G is 0 o'clock, the numerical value "0" is written in the display register A2, and the hour angle display 2 located above the printed numerical value "0"
c lights up. Thereafter, as the hour angle data changes, incremented numerical values are sequentially written into the display register A2, and the bar-shaped hour angle display 2c lights up sequentially in a clockwise direction.

Furthermore, in the next step S55, as a result of the above-mentioned phishing calculation, the number of lighted fish mark display bodies 2f is determined from the fish mark number data stored in the register N, and the data is written in the display register A3.

Then, in the next step S56, the display register A
The display section 2 displays the moon phase data, hour angle data, fish mark data, and time data stored in +, A2, and A3Aa.

If M=O is not determined in the mode determination in step S51, the process proceeds to step 357, and it is determined whether the mode register M is "1".

If it is the correction mode where M=1, then in the next step 358 it is determined whether the value of the register P is P=0 to 5. P=0
- 5, one digit of the month, day, day of the week, hour, minute, and second is the digit to be corrected, and step S
At step 59, the month, Sunday, hour, minute, and second data of the current time register X is transferred to the display register A4, and the digit to be corrected is displayed blinking.

In the determination in step 35B, if P=O-5, then in step S60 it is determined whether P=6. P
If =6, the year digit is the digit to be corrected, and in step S61, the month, day, day of the week, and year data in the current time register X are transferred to the display register A4 and displayed.

Further, in the determination in step S60, if P=6, the process advances to step S62. In other words, when P = 7.8 or 9, it is time to set the time difference from Greenwich, longitude, and latitude of the point where you want to know the monthly data.
Character data (GM
T, LO, etc.) as well as registers B and C of RAM9.

Display the time difference, longitude, and latitude data of D.

If M is not 1 in the determination at step S57, it is determined that the display mode is for the sunset time of 87 on day M-2, and the process proceeds to step 363, where "1" is set in the display register AO.

Then, in the next step S64, moon phase data for display is calculated from the moon age data in register E, and the data is transferred to display register A1.

Furthermore, in the next step S65, based on the date data and the time difference data, sunrise and sunset time data for the area with the time difference is read out from the ROMII and displayed in the display register A.
4 and display those data.

Returning to FIG. 5, when any key is operated in the bolt state of step S1, the process proceeds to key processing of step S17.

This key processing will be explained in detail based on the flowchart of FIG.

First, in step 371, it is determined whether or not the 1 key has been operated. If the K1 key was operated, it is determined in the next step S72 whether the value of the mode register M is "0". If 0M=0, it means that the 1 key was operated in the time display mode. Next step 3
In step 73, register P is set to "0". The reason why register P is set to "0" is to start the correction target technique from the second digit of P=O when switching to the correction mode.

Furthermore, in the next step 374, the mode register M is set to “1”.
” to switch the operation mode from time display mode to correction mode.

Furthermore, if M=O is not found in the determination at step 372, the process proceeds to step S75 and it is determined whether M=1. M
If =1, it means that the 1 key is operated in the correction mode, and in the next step 76, the above-mentioned lunar hour angle calculation, lunar age calculation, and phishing calculation are executed. Then, in the next step S77, the mode register M is set to "0" to switch from the correction mode to the time display mode.

Here, when switching from correction mode to time display mode, moon hour angle, moon age, fishing calculations, etc. are performed because information such as time, time difference, longitude, latitude, etc. may be corrected in correction mode. This is to calculate the moon phase, moon hour angle data, etc. based on the new information set at that time.

If it is determined in step 371 that the operation is not a 1-key operation, the process proceeds to step 378, where it is determined whether or not the operation is a 2-key operation. If the K2 key is operated, proceed to the next step 37B.
Then, it is further determined whether the value of the mode register M is "0" or not, and if M=O, "2" is set in the register M in the next step S79, and the mode is switched to the sunset time display mode on the 87th day of the day.

Further, if M=O is not determined in step 378, then in step S80, the value of mode register M is "2".
Determine whether or not. If M=2, the next step S8
1 sets register M to "0" and switches to time display mode.

FIG. 14 is a diagram showing the transition of the display state when the above-mentioned 1 key and 2 key are operated.

As shown in the figure, in the M-0 or M=1 mode, the time display mode and correction mode can be alternately switched by pressing the K1 key. For example, in the time display mode, along with the date, day of the week, and time, the phase of the moon at that point, the hour angle of the moon, and any fish mark data are displayed.

In addition, in the mode of M=O or M=2, the K2 key can be used to alternately switch between the time display mode and the 87th sunset time display mode. For example, the 8th of the day
In the 7th sunset time display mode, the 87th sunset mark display 2b lights up, and the dot display 2g of the display section 2 displays the moon phase (moon age 22.4 days in FIG. 14) along with the moon phase and moon hour angle. ) is the upper segment display body 2h
The sunrise time (same as 5:25 PM) is displayed on the lower segment display 21, and the sunset time (same as 8:03:05 PM) is displayed on the lower segment display 21.
Each minute is displayed.

Returning to FIG. 12, if it is determined in step 37B that the operation is not the 2nd key, the process proceeds to step S82 and it is determined whether or not the 3rd key is being operated.

If the operated key is 3, then step S8 is performed.
3, determine whether the value of mode register M is "1",
If M=1, register P is incremented in step S84.

That is, in the correction mode, the correction digit can be advanced to the next one by operating the K1 key.

Further, if it is determined in step S82 that the 3rd key is not operated, the process proceeds to step S85 and it is determined whether the 4th key is operated.

If the operated key is 4, it is determined in step S86 whether the value of the mode register M is "1", and M=1.
If so, in the next step S89, processing is performed to correct the data of the correction digit specified by register P.

Furthermore, if it is determined in step S85 that the 4 key has not been operated, then the K5 key or the 6 key has been operated;
Proceeding to step S90, other key processing is executed.

FIG. 15 is a display state diagram showing an example of time correction and input of time difference, longitude, and latitude in the correction mode. When you switch from the time display mode to the correction mode by operating the Kl key, the date, day of the week, and time are displayed as shown in Figure 15 (1), and first the second digit blinks, indicating that it is possible to correct the second digit. Become.

Thereafter, each time the K3 key is operated, the correction digits advance sequentially through the minute digit, hour digit, day digit, month digit, and day of the week digit, and each digit blinks, allowing correction using the 4 key. If the 3 key is operated again in this state, the year data will be displayed blinking in the digit where the second data was displayed, as shown in FIG. 15 (2), and the data in the year digit can be corrected.

If you press the 3 key again in this state, the letters rGMTJ will blink on the dot display 2g, the segment display 2h to the right will also blink, and you can press the K4 key to
The time difference with MT can be input. Figure 15 (3) shows G
This shows the display state when the time difference between MT and New York Daylight Saving Time -4 hours is input.

Furthermore, when the K3 key is operated, the letters "LO" indicating the longitude are displayed blinking on the dot display 2g, and the segment display 21 at the lower right also blinks, allowing manual control of the longitude. FIG. 15 (4) shows a display example when the longitude of New York, 74° east longitude, is input.

Furthermore, when the K3 key is operated, the characters rLRJ representing the latitude on the dot display 2g are blinking, and the segment display 2h on the right is blinking, making it possible to input the latitude. FIG. 15 (5) shows an example display when the latitude of New York is input at 41°.

The above-mentioned latitude and latitude data are corrected by 1 degree each time the four keys are operated. Therefore, when fishing or the like in the vicinity of New York, accurate hour angle data of the moon at that location can be obtained.

As described above, in the above embodiment, when calculating the hour angle of the moon, first calculate the hour angle data of the moon at Greenwich,
Furthermore, since the hour angle data is converted into hour angle data of the target point based on the position information, processing such as hour angle calculation and moon phase calculation can be simplified.

Therefore, it is possible to realize a lunar data display device that can easily calculate and display the hour angle data of the moon at any point on the earth based on the time difference with Greenwich and position information such as longitude and latitude data.

Although the above embodiment has been described for the case where it is applied to an electronic wristwatch, the present invention is not limited to this, and may be incorporated into a small electronic calculator, a data bank, a scheduler, an IC card, etc.
Of course, a dedicated device that displays the hour angle, moon phase, etc. may also be used.

In the above embodiment, the current time data is used as the time data, and the position data is set using the 4 keys. It is also possible to input position data and calculate the hour angle of the moon based on the input data.

Furthermore, the calculation timing of the moon age, hour angle, etc. is not limited to the daily position or hourly unit as in this embodiment, but may be calculated at shorter time intervals, for example, every minute. You may also calculate the angle.

Further, the display of the hour angle data is not a graphic display as in this embodiment, but may be a digital display of hours and minutes, for example.

〔Effect of the invention〕

According to the present invention, it is possible to calculate lunar data consisting of lunar phase and lunar hour angle data at any point on the earth, and display the lunar data obtained by the calculation. You can easily obtain reference data.
