Sun

Explore solar position, altitude, sunrise and sunset by location, with solar limb, refraction, elevation, horizon and obstruction controls.

Compare solar geometry from side and observer perspectives. Research controls include solar disc and limb definitions, atmospheric refraction, observer elevation, city radius, terrain and obstructions.

Solar altitude, direction, meridian transit and sunrise/sunset depend on the selected model and calculation profile. Experimental page overrides can intentionally differ from shared site settings.

Jewish Cosmology is an interactive research and educational web application connecting Hebrew dates, traditional Jewish calendar calculations and halachic concepts of time with the observable motions of the Sun, Moon and planets, astronomical seasons and eclipses.

JavaScript is required for the interactive explorers and calculations. The descriptions and navigation remain available without JavaScript.
