Get ready for galilean satellites occultations season! | International Year of Astronomy in Ireland | Astronomy 2009

Get ready for galilean satellites occultations season!

hs-2004-30-a-large_web

The observing season of Jupiter's Galilean satellites (Io, Europa, Ganymede and Callisto) occultations start in Ireland on the 24th of July and end on the 11th of November.

The occultations are seen from Earth only once every six years.

This is a special IYA project. See the page dedicated to the observers who never made such observations.

Think you're up for it? Continue reading and get prepared. See example of good observations by Hristo Pavlov.

An even more rare event (the following will be visible from Europe in more than 200 years from now) happens on the night of the 3rd to the 4th of August: occultation of a 6m star by Jupiter.
