LBT OSU/RC Partner OBserving Notes Date: 2015 April 21 UTC Observers: OSURC - Croxall, Tie, Verbescier Support Astronomer: Olga Kuhn (on-call) Telescope Operator: Steve Allanson SUMMARY: Threatening clouds filled the first half of the night. When they finally cleared we were able to get a couple object that were still up. Seeing stayed stable around 1". We had a power outage that shorted the first OSU_M101_1 exposure by 2 min. But the data looked fine. So we reacquired and set n=5. Programs completed are: OSU_M101_1 OUS_M101_LS3 Observing Notes: (All times are UTC unless otherwise noted) 01:06 OSU_M101_1 cals 01:19 OSU_M101_7 cals 06:52 Opening up telescope Pointing and collimating 07:08 M101_1.acq 07:20 M101_1.obs Seeing 1.0 07:40 Power glitch - stopped exposures 07:50 M101_1.acq 08:03 M101_1.obs Seeing 0.92 08:31 Seeing 1.04 09:00 Seeing 1.03 09:31 Seeing 0.92 09:55 M101_LS3.acq 10:09 M101_LS3.obs Seeing 0.80 10:44 Seeing 0.84 clear skies 11:16 Seeing 0.88 11:20 bd332642.acq 11:25 bd332642.obs Seeing 0.83 11:40 Closing up telescope 11:42 Putting mods to sleep
