Overview
The Solar Eclipse Calculator widget is used to compute the local circumstances of any solar eclipse from 1970 to 2099. It is localized in English, French and Chinese.
To use it first select an eclipse from the top pop-up menu, then enter the latitude and longitude coordinates and altitude of your observation location before clicking on the "Calculate Eclipse Circumstances" button. Times are given in Universal Time (UT), but you can select the time zone to have the local time.
The world map at the bottom right will show your location as a red cross and the links at the bottom left will let you access interactive Google Maps or Google Earth files of the eclipse.
