Jupiter, GRS region Nov 18th.

Hi All,

Imaged Jupiter this morning, the seeing overhead looked good but down around 30 degrees alt it was a struggle but still have some interesting detail. Have attached 4 742nm IR & 3 RGB data sets. Each RGB is over 11 min's and derotated in WinJUPOS.

I note a quite bright spot in both IR & RGB in the NNTB, it is close to the CM in my 14:09 RGB. Trailing this spot but higher on the Northern edge of the NNTZ is another bright spot, slightly larger. The colour of the GRS is certainly darker than the last time I imaged it back on Oct 12th. The region trailing the GRS remains chaotic and there are 4 small white ovals resolved in the STB. The distance between Oval BA and the dark spot trailing also seems similar to the separation in my data from Oct 12th.

Have not had many opportunities to image Jup this apparition in anything better than horrendous seeing but I live in hope.

Regards
Trevor
