Hi Guys
The Spot first noted on Saturn 9-29-02 is still present. The URL below is a
montage from six image sets that are from 10:14 UT to 11:26 UT on October
the 7th. The original spot located at about 41 degrees South latitude can be
seen rotating toward the CM in the sequence of six images. In the last two
or three images it is suspected that atleast two other spots are present one
following the original a few degrees and about 10 degrees further north and
the other at about the same longitude as the original spot but much nearer
to the equator.

Amazingly the seeing was excellent 9/10 even though a cold front was only
hours away from passing through Houston Texas. Transparancy was generally
good 6-8/10 but was hampered by some high thin clouds that were passing
through, It was a very steamy early mourning with heavy due and a light
South wind and lots of mosquitos all of which probably carry the West Nile
Virus!
