Date: Sat, 21 Dec 2002 06:18:43 -0000 Hi all, Here are some Jupiter images from this morning. The GRS area was presented. The array of SSTC ovals is prominent, though they are all still well seperated from each other. The NTB appears rifted, though the NTBn at these longtiudes is very faint. Also note a small dark spot on the n.f rim of the GRS, which must surely be rotating around it.

I think of particular interest here is the seeming overriding of the southern perimeter of the GRS by a skewed streak or belt, likely an offset of the STB; pr. the GRS it is angled northward in latitude, while fol. the spot it is elevated toward the south and appears to merge into a strong barge-like feature within the STB proper. Unless my eyes are playing tricks, I am of the impression that a very faint "veil" of sorts accompanies this skewed streak or belt on either side, north and south; the northern veil does appear to occult slightly a very much faded GRS hollow border. Note also how this same angled feature pr. the GRS does appear to intrude on currents within the STrZ, creating a bit of activity within that zone near the pr. end of the streak ahead of the GRS. Beautiful images Damian. Clay ---------------------------------------- Dr. P. Clay Sherrod drclay@arksky.org Arkansas Sky Observatory MPC/cbat Obs. H43 www.arksky.org
