Map

Eclipse Map

This section of the app allows you to view where the solar eclipse will be seen on Earth, animate the Moon's shadow, and plot the Moon's shadow in real-time. With an active internet connection, a very detailed map is displayed. When no internet connection is available, the app enters an “offline” mode and a less detailed map is available.

Basic Info (Upper left corner)

Basic eclipse information will be displayed in the upper left corner of the map.  The coverage, magnitude, and the mid/maximum eclipse time for the selected location will be displayed.  "No Eclipse Occurs" will be displayed if the selected location does not experience an eclipse.  If a total or annular eclipse occurs at the location, a duration of annularity/totality will be displayed in minutes:seconds.  

"Realtime " will be displayed instead of "Mid Eclipse" if the eclipse is actually in progress on Earth. 

"Animating" will be displayed instead of "Mid Eclipse" if the app is currently animating the entire eclipse.  Press the "Mid Eclipse" button in the lower left corner to stop the animation and return to the "Mid Eclipse" display.

Map Controls

Layer Button (Upper right corner)

Touch the "layer button" to change the map layers between a street, terrain, or satellite view of the map.

Center Location Button (Lower Right corner)

When the Center Location button is active (filled center circle) the map will automatically center on your current GPS position or manually selected location. To freely move the map, click the sticky button. To recenter on location, click the sticky button again.

Manual Location

Long press anywhere on the map to change the selected location to a desired position on the map.  GPS mode will turn off.

Eclipse Area of Visibility

The larger area marked by light grey lines indicates the part of Earth that will experience at least a partial eclipse. You may need to zoom out to see this entire area.

If a total or annular eclipse occurs, a smaller path marked by black lines indicates where a total or annular eclipse will be visible.  This path is typically no wider than 200 miles or 350km wide.

Eclipse Shadow

When the eclipse is not occuring and the app is not in "Time Travel" mode, the Moon's larger penumbral shadow is displayed as would been seen during the mid/maximum point of the solar eclipse at the selected location.

If a total or annular eclipse occurs, the Moon's (ant)umbral shadow will also be displayed.  

Note: The Moon's shadow will move dependent on the currently selected location.

Animate Button (Lower left corner)

Touch the “Animate Button” to view an animation of the Moon’s path during the selected eclipse from your specific location.

NOTE: Currently this function is an estimate of the Sun and Moon's position. Differences between what happens in the actual eclipse and what the simulation shows may be seen. Further updates may refine the simulation.
