About this app

An ephemeris gives the positions of naturally occurring astronomical objects in the sky at a given time for a given position. The Sun Ephemeris gives you the accurate position of the sun and the moon at any time for any location on earth. The Sun Ephemeris is ideal for landscape, nature, travel and outdoor photographers. It combined a map-based approach to search for any place on the planet with a compass based approach to easily find the direction of the sunset, sunrise, moonset or moonrise.

Key features
Sunrise, Moonrise, Sunset and Moonset time and azimuth
• Live tracking of Sun and Moon position
• Sun & Moon elevation graph during the day
• Sun and Moon azimuth and elevation at any time during the day
• Use compass to find sun/moon rise/set directions
• Graphical display on a map (Standard, Satellite, Hybrid, Terrain)
• Search for places by name
• Moon distance from earth
• Moon phase and illumination
• Solor noon time, azimuth and elevation

1. Find your location

Use the map view and move it to your current position or use GPS to center the map at you exact location. You can also search for any place in the world by entering its name... Sun and Moon positions are then automatically updated using the choosen location.

2. Set desired time

Use the calendar controls to change the date and time. You can jump from one day to another or from one week to another or use the date time picker to select the date you want. Then you can use the elevation graph to adjust the time within the day. At any time, you can rewind/forward to the current date time which will activate live mode (which follows your phone's clock).

3. Find directions

Use the Compass view to get the direction to Sunrise, Sunset, Moonrise or Moonset for the selected location and date.

Enjoy the moment !

Just installed this morning. So far, with some guessing because there appears to be no Help file, it works great. A legend for the map would be useful. However, those items being noted, this ephemeris, when allowed access to your GPS, provides data without advertisments👍 and seems to be quite accurate in detecting your location. The movable timeline and time advance buttons are a great what-if feature too.

Great app! It allows you to easily tell where the sun and the moon is, where they are going to be, when twilight is going to occur, and gives you the various angles that are concerned at all these points. There's a slider that allows you to easily slide through the various times and angles, and you can easily go to any time of the year. via a "date picker." This is a very practical app; it also helps you to intuitively visualize how the Earth and Moon's position is related to the position of the Sun. You might only use if for practical purposes, but it it will make you curious as to the science of it all. Non-nerds -watch out, you might become just a tad nerdy. Or not. I love this app!

Great tool. Data is accurate and easy to use. Only thing I would like to see is ability to differentiate between magnetic and geographic north, or a tool to determine declination at current location to make sure compass is accurate. The compass overlay was not agreeing with either of a physical compass or another compass on my device and it did not respond to calibration attempts. Love the app, though.
