SAROSIUM, an Eclipse Tracker with Its Equations on the Table
A browser-computed atlas of every solar and lunar eclipse from 2000 to 2100, with a zoomable 3D globe, shadow paths, and local timing.
Field notes
The page separates event discovery from displayed calculations: astronomy-engine finds candidate eclipse dates, while JPL DE441 vectors supply the positions used for the visible geometry. It serves 458 data windows around events, interpolates position and velocity with cubic Hermite curves, and models observers on the WGS84 ellipsoid. A validation control reportedly recomputes comparison figures in the browser, with one off-grid check listing sub-0.03-arcsecond differences for the Moon and Sun.
