FELEK Description

FELEK is a small screensaver that displays the trajectories that the Sun and the Moon follow on the sky. The latitude, trajectory speed (as a multiple of real-time) and the tail length is adjustable. The gray ellipse is the Earth surface. Furthermore, the Earth and Moon illumination is displayed, showing the variation in the distance and inclination of the Moon. The position on the Earth, selected by the latitude, is marked with a red dot on the upper-left globe.
