"Moonrise Time" is an app that shows the weekly time and direction of the moonrise and moonset for a specified observation site.
Functional overview
Specify the observation site on the map screen.
There are three ways to specify it.
Current location button
A long press of the map
A search to put in the name of your address or place name
Once the observation site has been chosen, by pressing the blue button of the present location balloon or pin, information for the next seven days will be displayed.
Moonrise time, azimuth
Time when the moon crosses the meridian, angle of altitude
Moonset time, azimuth
Number of days since the new moon (at noon)
Changeable terms
Observation site: Return to the map screen and specify the observation site.
Start date: Specify the start date of the forecast.
Elevation: Specify the elevation of the observation site in meters.
Time zone: Specify the local time of the city you wish to display.
Example: Japan has one time zone, so display Tokyo.
Understanding the forecast results
*The azimuth assumes north is 0°, east is 90°, south is 180°, and west is 270°.
*It assumes a flat horizon without taking into account the native terrain.
*The forecast results have several seconds of calculation error, which increases at high latitudes.
*The moonrise and moonset are calculated from when the center of the moon is on the horizon.
*A horizontal line through the time represents days when that phenomenon will not occur.
*The vertical latitude indicates the negative value of the west longitude and southern latitude.
