Jupiter Approaches Opposition from the Sun new
      #5532902 - 11/21/12 08:13 PM

Giant Jupiter has entered our evening skies as it grows in brilliance prior to its opposition from the Sun on 2012 DEC 02. Each day I update my timetable and array diagram for events involving Jupiterís four Galilean satellites. Preview graphics are presented for shadow transits.

My more detailed article describing the current Jupiter apparition along with more Jovian graphics and data can be found at: www.CurtRenz.com/jupiter

Descriptions and photos of Jupiter and its satellites would be welcome additions to this thread.

During the nights surrounding Jupiter's opposition, the transiting satellites will partially occult their transiting shadows. That will be the case this evening for Io and its shadow. This due to the Earth currently appearing near conjunction with the Sun as viewed from Jupiter. The alignment could lead to some interesting photos.

Curt, thank you. Just had the most amazing Jupiter opposition ever. Ganymede emerged from behind the limb, clean as a whistle. Beautiful sight.

The only opposition around here is the clouds as fog...

Cloudy all day yesterday, but cleared up at dusk.
Wife and I took quick peeks at Jupiter and moons with my ST80. I was pleased to see some nice detail with my 8.8ES82 eyepiece (45x).

I bet it would have been amazing with my 8" scope, but there wasn't enough time before the football game for set-up and cool down

Cheers,
David

Curt,
Is it possible for the bright transiting moon to just momentarily occult its shadow. On Dec 2nd, I was watching an bright/shadow transit of (I think) Europa and momentarily saw a bright flash of light within the dark shadow. Just lasted for a moment though. Could it have been the moon itself I momentarily saw in the transiting shadow?

/Ira

Ira, if you mean during the middle of the night of December 2-3 Israeli time, those were Io and its shadow transiting. Only a crescent of the shadow would have been visible as it appeared to hug the north limb of Io. This would have been the case during the entire two-hour transit, not merely for a moment.
