Did I see the dark plume heralding the SEB come-ba

Attached is a sketch I made the night of Nov 7, 2010. At the time I just wanted to catch Io's transit and shadow across Jupiter but I kept noticing a high contrast area that was distracting. I made a note of it but didn't think anything of it. Then i saw Christopher Go's image of the dark plume on and thought "did I see that?" Does anyone know how I could confirm this--perhaps back-track the rotational period back to Nov. 7th and see if the dark plume lands on the meridian (which is where I have it drawn)? Thanks!

Hi Paul,

In my image during Nov 7, the outburst has not started yet. The area was still methane dark. The outburst must have occured around Nov 8 (which is the last image without the plume) and my discovery image.

I tell you what, I was observing Jupiter with my 7" mak-Newt this evening, being blessed with very steady and clear skies for the last couple of nights, and I was seeing a lot of activity in the SEB area at ~7:00 to 8:00 Eastern time USA. Looked like several long filaments and the band was less muted.

Maybe something IS going on.
