A heads up for observers in the Eastern U. S. and Canada. The moon will move in front of Jupiter during the predawn hours on Tuesday, December 7, high in the southeastern sky. In the Northeastern Corridor this will occur between about 4 and 5 AM. You can check for exact times at Sky & Telescope's website.
You'll want to get out at least a half hour before the occultation begins to see the crescent Moon almost on top of bright Jupiter, then watch as the Moon devours the planet. About an hour later Jupiter will emerge from the dark limb of the Moon.
