Interesting developments in Jupiter's GRS...

About this image

Hi all,

Attached is an observation of Jupiter I made with Dr Hugh Sasse using the University of Leicester's 20 inch Planewave D-K telescope. Some very interesting developments in the GRS:

The GRS was clearly distorted on the prec. side- The RSH is no longer white and seems to be filled with darker material. I had the impression that the spot was also interacting with material from the STB but I am not certain of this. The spot looks larger in the drawing as it was considerably difficult to trace the outer boundary on the fol. side.
There seems to be a dark belt in the STropZ (is this a STropB?) which is interacting or at least progresses up to the GRS at this longitude.
EZ is still rather dark and a number of blue festoons were apparent.
NEB very active.

I studied the GRS further at x230 with a W#80A filter from 0121 UT to 0128UT and obtained a strip drawing the GRS and its environment, alas due to the poor seeing by that point it doesn't show any more than the disk drawing here. Looks like this will be an interesting Jupiter apparition!

Best wishes,

-Paul
