David Arditti (355mm SC)
This set is slightly marred by an artificial mark in the N hemisphere in some of the shots due to dirt on the chip. However, the SEBZ spot is faintly shown, confirmed by two R images 9 mins. apart., at an estimated III=210. I estimated it on April 28 to be at III=57, so it fell behind System III by 153 deg. in 21 days, at 7.3 deg. per day. (Marc Delcroix estimated 7.1 deg. per day in an email on 6 May). I may get more data on this when I go through the rest of my unprocessed images.
