Total Solar Eclipses - $1.99
Total and Total-annular solar eclipses happening between 1900 and 2100, exactly 287 eclipses from May 28th 1900 to September 4th 2100. The program gives the times in Universal Time of the Solar eclipse phases (initial, central, and final) and the geographical coordinates from where it is possible to observe those circumstances of the eclipse. It also gives maximum duration and the width of the lunar umbra. The longitude and latitude of seven points of the lunar umbra path on the Earth surface are listed.

The program has a few functions: Earth Map, Movie and Google Map visualization. The first allows the viewing of a few points of the path of the lunar umbra on the Earth surface; the second creates an animation: the user will see the eclipse from one hour before up to one hour after its maximum phase with a step of 2 minutes; the third function is a Google Map of the area around the point where the eclipse reaches the maximum or the phase selected by the user.

Moreover it is possible to change the geographical coordinates of the observer. This allows knowing if and how the eclipse will be seen from other points of the Earth surface (e.g. it is possible to know if the eclipse will be partial or it does not occur for those coordinates).
