IMPORTANT DEVELOPMENTS NEAR BA/GRS -
"1st image" - Seeing good; note the beautiful festoon activity within the
NEZ and the very dark NEW gray streak/bar on the s. edge of the NEB, just on
the CM! Of most importance is the incredibly rapid development of features
and transient activity just preceding the GRS in the STrZ. Note evidence of
another less distinct oval of the same latitude as BA just pr. BA and
slightly pr. and south of the GRS; several smaller white features are also
identifiable within this immediate area. VERY interesting interaction just
N. of the GRS with the SEBs component which appears to wrap "under" the
perimeter of the spot.
"2nd image" - Seeing fair. The intense dusky activity and features pr.
the GRS are seen in this image. Note very large and dark gray equatorial
festoon emanating from the dark bar/streak on the NEBs edge.
Well, this last image is unique....it was literally taken through clouds;
normal exposures of 1/13th second suddenly became 1 second.....nonetheless,
there is some salvageable imaging here. Note the dusky light oval just east
of the CM in the NTB; the darkening fol. oval BA continues to intensify;
some detail and brightening of BA is suggested.

Hi Jupiter Observers,
Here is an observation from Feb. 15th 2002. The oval BA can be seen to be
almost at the same longitude as the GRS. It has a rather flat border on its
S. side and the boundary where it meets the GRS is darkened. Many white
spots and festoons are visible.
The sky was very transparent, 9/10, and seeing was good, 7/10, with a 3 MPH
SE wind. No dew was present.

Here is an enlarged section of images sent from the 2-15-2002 observation
showing the GRS and the oval BA. The boundary between the GRS and the oval
has a "gap" in it possibly indicating some increased interaction beteen the
two.

Hi all,
Here are some Jupiter images from the second night. The STrZ oval and GRS area was presented during the session. The
material of the South Tropical band is certainly dissipating. Also note the small STrZ oval, appearing quite bright. Oval BA
and various SSTB ovals are also well followed. Note the NEBn edge is noticeably receding and breaking up now.
Best Wishes
Damian
