Summary
Brian Colville (300mm Schmidt-Cassegrain, Pixcel 237 CCD Camera)
I have attached images taken of Jupiter on Dec 19 between 01:44 UT and 03:32 UT. The GRS was approaching transit during the final images. I became clouded out shortly after the final images. There are six infrared images and 3 methane band images.

Seeing conditions were quite variable, and by the end I could not get a decent methane image since exposures were 10 sec long and were affected by the seeing. Nice detail in the IR image taken at 03:02 UT.
