The Green (G) channel was synthesized from an average combine result of the R and B channels. This technique is nicely described by planet imager Antonio Cidadao here: http://www.astrosurf.com/cidadao/red_blue.htm
This is an enlargement of Io from the above image
Below is a rotation animation from the same night, spanning a 3 hour period from 2:30 to 5:30 UT on 5-30-06
Although I usually present my planet images south up to match the view in an inverting telescope, I've presented this 13 frame animated GIF with north up... it simply looks better to me this way as it looks 'more natural', as many of us know most planets rotate from west to east. As the animation progresses, the Great Red Spot (GRS) moves from left to right closely followed at it's lower left by 'Red Spot Jr.', which is a 1/4 size version of the GRS. The moon Io is also seen to merge in front of Jupiter, closely followed by it's shadow.
Each frame is a processed result from 2 separate, R and B filtered 50 second long webcam videos; each R and B pair separated by a period of 15 minutes.
