Seeing 7 out of 10. Some thin, high clouds drifting over Mars. Cool, calm, classic DC start of fall weather. Surprisingly good seeing since a cold front only recently passed through. Much better detail then on 9/6 (as good as that was!).
South Polar Cap showed both pieces broken off, dark "shadows" under the pieces as well as the main cap. And, the "remains" of the dark collar that was so visible two months ago was clearly seperated from the SPC. Otherwise, no real sign of weather. Normal brightness in Hellas, and off Sinus Meridiani. Very nice collar around northern part of Hellas and very good detail in the southern part of the basin. Ismenius Lacus in the far north seen in moments of good seeing. Dark markings were suprisingly visible in W47 (blue)filter, but no apparent clouds.
