Tonight's sketch was made under challenging conditions, with a lot of time spent waiting for convective cells of boiling air to pass over. Not a lot of detail to see as a result (Seeing 4A to 5A). Here's my latest capture compared with a previously posted sketch to show how much change there has been in the vicinity of the GRS. There was the usual 'bow' wave of cloud, with the GRS appearing to 'float' on its outstretched palm, but I couldn't make out the SEB in the wake of the spot at all,except for a bunch of turbulent swirls. I heard about this recently and wanted to see for myself. Yup! There is was!

Anyone else sketching this?

Congratulations.

Ian,

 

Very nice side by side. Jupiter's appearance changes much over intervals of just weeksVery nice work.

The SEB is rather bright now, and the GRS has darkened in the last years. At weekend I saw the spot in bad conditions: Jupiter stood only 10 degs in the sky. But the GRS was a distinct object.

Any drawings of the GRS Uwe? I would be interested to share what you've been observing! Telescope.gif bugeyes.gif

That’s excellent sketching and great detail showing the changes to the GRS region :D
