A rare sky event is going to occur in the early morning hours on Sunday, July 15th 2012. The Moon will pass in front of the planet Jupiter and its four moons and will block them from our views for about an hour. The phenomenon that astronomers call “occultation” will start at 3.30 a.m. Half an hour later at 4:01 a.m. the moon will cover Jupiter and it’s Galilean satellites (moons) over the course of a few minutes, blotting them out of the sky. About an hour later they will pop out from behind the moon one by one.
The phenomenon will be best visible from Middle East and Africa, but also from parts of South European countries, like Greece.

“These occultations are memorable events just when seen with the
naked eye. The proximity of so many bright heavenly bodies near each
other is one of the most beautiful sights the sky has to offer. Through
any kind of optical instrument the grandeur is even greater. You will
need at least binoculars to see the Galilean satellites occulted. A
telescope, of almost any size, will show much more, including the
cloud-striped disk of Jupiter as it slides behind the bright,
crater-scared rim of the moon and reappears from behind the dark side of
the moon. I remember every occultation I have ever observed and
treasure them as my dearest astronomical memories. You don’t have to be
in Miztpe Ramon to see this, or even have especially dark skies. But you
will need a very clear eastern horizon, since all of these objects will
have just risen about 30 minutes before the occultation begins,” writes
astronomer Ira Machefsky .

PS In winter 2010 I witnessed a rare night sky event occurring
right in front of my window: an extraordinary play of the Crescent Moon,
Venus and Jupiter, I think playing ‘seek and hide’ for about one hour…
Amazing!
