Montage of data available from Eclipses Online

This web site has been designed to provide information on the global and local visibility of solar and lunar eclipses. For example, the montage of images on the left illustrates the type of information available from Eclipses Online. Shown here are the partial eclipse of the Moon on 2005 October 17 and the annular eclipse of the Sun on 2005 October 03 including an eclipse animation and the local circumstances for Madrid in Spain.

The mapping information presented in the following pages is based on data derived from solar and lunar eclipse software used in the production of The Astronomical Almanac.

You can find information on eclipses for a range of years running from 1501 CE to 2100 CE inclusive. In this interval there are a total of 2881 eclipses made up of 1421 solar and 1460 lunar eclipses.

WARNING: Observing solar eclipses can be dangerous if you do not take appropriate precautions. The Sun is a powerful object capable of doing irreparable damage to your eyesight. The only time it is safe to look directly at the Sun is during totality. At any other time, the ultraviolet and infrared radiation will damage your eyesight even though you may not feel any discomfort.

Aluminized mylar eclipse viewers in useIn addition to a number of techniques for projecting the image of the Sun onto a screen, aluminized mylar viewers can be used to observe the partial phases of a solar eclipse directly. Please be sure that they are certified under the provisions of the Personal Protective Equipment (EC Directive) Regulations 1992/2002 for the United Kingdom and Council Directive 89/686/EEC for the European Union. Only viewers carrying the "CE" mark have been tested under these regulations.
