Crescent Visibility Screen Saver





EHILLE is a tiny screen saver drawing the visibility of the new crescent on the earth map.

The start date, probability of visibility, processing speed and dwell time between scans can be adjusted. The visibility map for the nearest crescent is displayed. The latitude/longitude as well as the time of the first visibility together with the hijri calendar, the real-time values of the moon phase angle and the crescent width are shown. The instantaneous visibility as well as the cumulative visibility can be sketched. Determination of the crescent visibility is based on the Alperen criteria.

You can install the screen saver by right-clicking on the SCR-file and selecting "Install". Program parameters are saved in the INI-file.
