Never opened. TR2 rotator "zeroed" at -90 beginning of night. During SPIcam cals one filter, strom v, seemed to have a strange obstruction. See file /Q3UW08/UT080910/dflat.0003.fits. I took the wheel out inspected it. Saw nothing wrong with it. Put it back in and seemed to be fixed(?) Beginning cals with Agile, Nancy clicked Abort on a sequence and it seemed to lock up the expose. I tried restarting nubs and taking a test exposure. It would start an exposure and then abort it repeatedly. It was as if every Abort click was saved up and after enough expose attempts went through it cleared. We did a trial run for the LCROSS program and worked out some of the procedural kinks. The file names do in fact increase a digit when you go above 9999 files. But we discovered that taking 3000 0.3 second exposures produces a negative effect through the TUI gui: the exposures actually finish before the timer and incremental seq status can count up. Therefore not allowing a new exposure sequence to begin until the counter has finished (approx. 10-15 minutes later).
