Welcome to Eclipses Online

Eclipses Online is HMNAO's canon of eclipses which contains a wealth of information on solar and lunar eclipses past, present and future.

In conjunction with the US Naval Observatory, we have provided a canon of eclipses based on software used in the production of The Astronomical Almanac. This canon provides global and local circumstances, animations and eclipse panoramas for partial, annular, total and hybrid solar eclipses in the period 1501 CE to 2100 CE. Similarly, global circumstances of penumbral, partial and total lunar eclipses are available for the same period. Most of the information can be downloaded. Search for an eclipse!

For those of you who want to access material on the old UK Eclipse Group web site, it is still available. However, be warned that some parts of this site are more than five years old and some links may no longer be valid. Refurbishment of these pages is planned and will be carried out in the near future as both time and effort permit.
