Awful weather. We can identify the eclipses during a better patch 130min into the run. Guide star lost at end - last few frames are junk
run028   SDSS J065133.33+284423.3   30/10/2011   01:28:11 01:36:50 269 data caution 2-WIN 1000.5 1935.5 u' g' i' 1 250 x 320 192, 615 1 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2011B/N11 Groot vsd,cmc,tk 100222   run028   Acquisition. Slight delay afterwards for a derotation
run027   SDSS J012940.05+384210.4   29/10/2011   21:32:50 01:24:05 1382 data FFNOC 8500.5 10046.7 u' g' i' 2 1024 x 1024 2 x 2 CDD 8C0000 -40,-40,-40 3590 W/2011B/N11 Groot vsd,cmc,tk 100222   run027   Set nblue to 2. Science data. Cirrus around and terrible (up to 5") seeing. Hint of variability of g'

Increased blue coadds to 3. Tried focusing but the start point seems pretty good. Awful flairy seeing up above 2" makes focusing very difficult. No signs of an eclipse
run017   SDSS J2349+3553   29/10/2011   19:30:12 19:42:02 235 data 2-WIN 800.5 3035.5 u' g' i' 1 400 x 500 100, 600 1 1 x 1 CDD 8C0000 -40,-40,-40 3590 W/2011B/09 Marsh vsd,cmc,tk 100222   run017   Science data, on target 23 min before the predicted mid-point of the eclipse. However, we didn't need to tweak the acquisition so the previous three data caution runs should also be good for science data, giving another 7 min.

Momentary panic before I realised I had it on clear. It's been a while since I've done any ULTRACAM observing...

We've been messing around for three days now due to read noise problems in the green arm. Things are mostly fixed now, although there is still some sign of pickup in the left side of the chip
