Hi all,

Here are a few red light images obtained tonight with Jupiter low in the
sky.

The "f" pair of SSTC ovals is still present although closer than yesterday
(my center to center estimate is 5 deg, but the actual value may be less
than that). The "p" oval of the pair is still slightly N than the "f" oval,
and the small spot that was present between them is now more visible (than
yesterday) but located N of the pair. Seeing was not as good as yesterday,
but I woul say that the ovals are virtually contacting with each other.

Hope to get better results two rotations from now, with the planet higher
in the sky.

Good observations

Antonio




Hi all,

Here are the preliminary images obtained just a few hours ago, in a session
with moments of good seeing but with slightly hazy skies. Europa and
Callisto were displaying a nice double transit (better seen in the IR and
methane images, but also in the color image).

In my opinion there is some evidence that the interaction between the two
SSTC ovals has already begun.  While two spots can still be seen (not as
clearly as yesterday alghough seeing wes better tonight), apparently at a
distance similar to that observed yesterday (about 2 rotations ago),
tonight the "p" oval of the pair was clearly less bright (with various
filters) and located N of the "f" oval. In addition, the tho ovals looked
slightly elongated in latitude (as an "internal control" the tiny spot that
follows BA and Callisto itself show the expected round shape). The "third"
oval (well seen yesterday and located N and between the merging pair) was
tonight much less conspicuous. It may also be relevant to mention the with
the clear and B filter there was no clear distinction between the two
ovals, and a slightly oblique short rod was seen. However, both these
filters showed well the tiny oval that follows BA and central detail in BA
itself. Unfortunately, since the sky was hazy, I could not get a proper S/N
ratio in the IR and CH4 images. The interacting ovals look do not look very
distinct in IR, and once again the CH4 image only shows a faint spot at the
oval's position (the CH4 image of BA continues to be smaller than its
visible counterpart). sho Hope that these dynamic changes are also been
followed at Pic and IRTF.

Visible in most filtered images, I would also like to call your attention
to the vertical elongated white cloud pattern that "bridges" the darker
material preceding the GRS. The center of BA is south of it.

Good observations to all

Antonio

i all,

I attach some IR filter images of the SSTB ovals passing the GRS we have been following. These were obtained
about 3-4 hrs ago, and clearly now show the ovals seem to be in contact. Seeing conditions were reasonable for
this image. Here is the image data.

Hi all,
there is today observation. SSTC WOS may have start to interacting. Porthole at south of SEB(N) dark
streak.
Good observations all,
