1月29日的Ephemerides应用程序分析

Ephemerides computes Sunrise, Sunset, Moonrise, Moonset times and Moon phase for any place and date of your choice. You have to choose the location of your interest, selecting it from a list of the main world cities, or capturing the current position detected by the internal GPS. Then you have to select a date; if you don't, the current date will be used. Finally, tap on the Compute button. The application computes and shows the results for the place and date you selected. Astronomical computations are very accurate, and keep into account moon perturbations, too.
