Journal Entry 5 Dec 2011 - Just give me 1 clear shot of Jupiter, Pleeeeese!

Oh, the weather is horrible and I feel a little jilted because this morning the sky was so clear.

Anyway, the clouds have thinned out and I can see Jupiter and moon though still through cloud.

Let's see if I can get another pick of Jupiter's Satellites for the Jupiter mass determination experiment.
