Hi Mars Observers
Here
is an image from October 11th 2003 at 03:08 UT. The sky transparency was good
7/10 and the seeing was fair to good 6/10.

Hi Saturn Observers
Here
is an observation from October 19th 2003. The spot at -29 degrees lat. can be
seen on the S. edge of the SEB preceding the CM. This spot was imaged by the
HST on Aug. 25th and has been shown to have a drift of -7.3 degrees/day. The
globe of Saturn shows quite a bit of detail in this image. Several dark
condensations (spots) can be seen at various locations on the globe. The sky
was clear, the transparency was excellent 9/10, and seeing was good, 7/10 with
a few moments when it approached 9/10. No wind and light dew. The weather was
cool with the temperatures in upper 50s F.

Hi Saturn
observers,
Thanks to the
very good images some observers are sending to the IOPW, we have been able to
confirm that the -29 deg spot tracked by Ed Grafton is the same that one of the
spot at this latitude captured with the Hubble on 25 August. This spot moves
rapidly eastward in System III (as expected). See graph W_29S.
The second spot
at -42 deg moves westward slowly (also as expected, see graph W_42S), and it is
in the place where last year convective spots formed.
The last image
by Ed Grafton (Oct. 19) show apparently small dark spots in temperate -
tropical latitudes similar to those captured by HST last apparition, but they
must be confirmed by their rotation observation. The image also shows features
in the Equatorial Zone. These are very important to confirm the drop in the
equatorial jet observed between 1996-2002.
Good
observations!
