Hi Jupiter Observers
Here is an observation from April 18th 2003 at 01:22 UT. The jet stream spot
seems to now be located directly north of the center of the GRS. The less
favorable seeing in the early evening is making the spot quite challenging
to follow.

Image data:
The transparency was fair, 4/10 and the seeing was fair, 4/10 with a
2mph S. wind and light dew. The weather was warm with the temperatures in the
low 80s F in the early evening.

Hi all!
After a 22 days long negative period, finally a fair opportunity to image Jupiter!
I pushed processing to put better on evidence the spot in the GRSH, at that moment
in the bottom of the hollow starting to "climb up" along it.
Hope this helps, my best wish you have a nice Easter!
