The Christmas 2012 Moon-Jupiter Conjunction

I blogged a couple of days ago about the Christmas Conjunction of Jupiter and the Moon. I even suggested today would be a good time to try for Jupiter during the day.

Unfortunately, in Tucson it was cloudy most of the day, especially later in the afternoon when the Moon and Jupiter would have been positioned for a daytime attempt. Early in the evening, the clouds were very thick and you could barely see where the Moon was in the sky behind the clouds with no sign of Jupiter.

After watching the Doctor Who Christmas special, I went outside just to check and see if there was any chance of seeing anything. Much to my pleasant surprise, there were Jupiter and the Moon surrounded by a 22 degree Moon halo! Needless to say that necessitated grabbing a camera and a couple of my wider angle lenses (since the radius of the halo is 22 degrees, that means I need a a lens with at least a 44 degree field of view to see the whole thing…fortunately, I have a couple that will do the trick). So here are the pics.
