There was no conspicuous change from Japan. There is a light part in
the south of Elysium(215W,;25) with the image of D.C.Parker. This is
thought to be the cloud of the ice.

Dear all - I imaged Mars October 21, 2003 at 3:26 UT.
The seeing was terrible with some patchy clouds around.
Also, it was kind of breezy. The adaptive optics was a great help to get a decent image.
