The Paris Observatory informs you about the total solar eclipse of March 20, 2015

Official ephemeris

At the Paris Observatory, the Institute for Celestial Mechanics and Ephemeris Computation (l’Institut de mécanique céleste et de calcul des éphémérides - IMCCE) provides the official French solar, lunar and solar system ephemeris.
Its internet site has the time at which the eclipse takes place in various French localities

Example, for Paris :

First contact between the solar disc and the Moon will take place at 9 h 22 min 29 s.
Last contact will occur at 11 h 40 min 11 s.
The eclipse will reach its maximal point, i.e. when the Moon has covered the largest possible fraction of the Solar disc (78% as seen from Paris), at 10 h 29 min 15 s.

A small pamphlet « 20 mars 2015 – une éclipse en lumière » will be published.
To mark this occasion, the IMCCE of the Paris Observatory, together with EDP sciences,will publish a pamphlet entitled « 20 mars 2015 – une éclipse en lumière » - it will be on sale on March 5th. Fully illustrated, it includes clear instructions for observing the eclipse : Where ? When ? How to observe it ? Vital precautions ? How eclipses are produced ?...
