Hi all, four more images of the planet, but seeing ranged
only from fairly good to fair.
I have again tried a W25A image (cp030107b).
While its overall quality is low, it shows one detail that
is odd to me.
If you look at the preceding half of the SEBn, you will see
like a "bay", and it looks like if some material of the
EZs was "invading" this area.
The color image (cp0301407a) taken only 11 mn before doesn't
show any "bay" but reveals discrete blue features in the
otherwise very white EZs.
Best regards
Christophe

I have made an observation of Jupiter on January 7, 2003 (05:50 U.T.).
Much detail was noted over the disk. I hope that you enjoy it. Any
comments would be welcome. The best of luck in your own
observations/images. I look forward to them in the future.
