Jupiter’s GRS in December

 Winter is here and with it colder nighttime temperatures. Don’t let that stop you looking at Jupiter; it’s in good viewing position as the night sky appears. I did have a fantastic view of Jupiter in the RC20 f/8.1 telescope one evening in October with near perfect seeing. Watch the white oval in the NEBs transit, the GRS and a red barge in the NTB transit later on. The GRS was seen easily with 26 mm and 15 mm eyepieces. A W82A filter gave a more pleasant view, while a deeper blue filter W47 made the GRS stand out on the planet. Even with those filters I could not see the Oval BA following that followed the GRS. A dusty region followed the GRS and was more southern in the STB. No sign the Oval BA was a darker red oval. I did manage to see, only once, a smaller white oval in the SSTB above the dusty region in the STB.

Nov 20, 2010 : I’ve kept the White Spot in the SEB,  added the SEB Revival Spot, and changed the longitide of Oval BA.

 These are only approximate transit times of current visible features. I’ll keep listing Oval BA in case it becomes a more easily target to see
