Open-source browser-only 3D simulator for the August 12, 2026 total solar eclipse

This specialized program is used to align and stabilize solar eclipse time-lapse photos.

Plan and automate solar eclipse photography: contact times for your location, timed scripts that fire Canon, Nikon and Sony cameras over USB (gphoto2), and a wizard that writes those scripts.

Javascript library for positional astronomy

Various scripts to calculate eclipses

Wavelength-dependent 4D model of solar eclipses using images of the Sun. Currently supporting annotated images from SDO AIA, SOHO EIT, GOES SUVI, Hinode XRT. Can be used for eclipse predictions and scientific analysis.

Interactive 3D total solar eclipse simulator with historical replay archive

Des del punt exacte on seràs: quants segons de totalitat veuràs de debò, a quina hora i cap a on mirar. Càlcul topocèntric, horitzó real del terreny i realitat augmentada ancorada al paisatge. Eclipsis del 2026, 2027 i 2028.

Agentic Eclipse Library: local eclipse calibration, stacking, corona filters and motion analysis. Codex plugin, Python tools and research notes. MIT.

Interactive map for planning the 2026-2028 solar eclipses over Spain: eclipse timing, terrain horizon and weather by location.

WebGL visualization code for Solar Eclipses

3D solar eclipse simulator built with Unreal Engine 5, a Python/Skyfield backend (JPL DE441 ephemerides) and Cesium terrain. It renders umbra and penumbra cones in 3D, computes C1–C4 contact times, and covers 71,264 solar eclipses and 72,272 lunar eclipses from 13,000 BC to 17,000 AD.

Custom solar eclipse viewer, with lots of info about the eclipse specific to your location.

Ephemeris-driven two-moon eclipse search, coupled N-body dynamics, and scientific visualizations

Every solar and lunar eclipse from 1900 to 2100, computed in the browser: type, time, path, duration, Saros, and what it looks like from your city.

A code I wrote to process my eclipse photos.

An app that applies filters to the Sun's corona
