LBT OSU/RC Observing Notes Date: 2016 Feb 09 (UT) Observers: Kevin Croxall (at Tucson Remote Facility) Support: Barry Rothberg TelOps: Gino Bechetti Summary: Beautiful skies at sunset. Clear as can be. Nearest clouds are in Mexico. Dry skies as well with seeing ~1". Had a bit of a temperature swing during the day so the mirror temps are abit uneven but not awful. Had some hiccups in seeing due to an inversion layer but then it settled. Swtiched to LBC just before midnight. Trouble due to the telluric acquisitions. Needed to inserst an additional time so the slit was visible in the slit image and then a ND1.5 filter to not saturate the star.

Went MUCH smoother! UT 04:29 OSU_KDdivBLRqsos/J0833 seeing ~0.9" UT 05:11 seeing jumped up to ~2" UT 05:25 OSU_KDdivBLRqsos/J0835_tellstar seeing ~1.5" UT 05:45 OSU_KDdivBLRqsos/J0835 seeing ~1.3" UT 06:05 seeing stabilized ~1" UT 06:41 Switching to LBC having some trouble with power to the swing arms... Gino resolved the issue but we lost about ~15min UT 07:21 Running focus & collimation UT 07:30 OSU_monitor/N3077 seeing ~1", skybrightness 22.04 UT 07:49 UVa_Segue1/Seg1mos01 UT 08:27 stopped half way through the ob abd redid the focus as it was slipping. Made a new ob that starts at the 6th dither. UT 08:32 restarted the OB blue guider failed after 5 dithers... re-edited to perform only the last dither restarting the last dither blue had trouble for a bit then 20sec in found its guide star and was fine... seeing ~1.5" UT 09:20 OSU_monitor/I2574 seeing ~1" UT 09:42 OSU_monitor/N4236 UT 10:03 OSU_monitor/N4605 seeing ~0.9" UT 10:24 OSU_monitor/N4449 UT 10:45 OSU_monitor/N5474 seeing ~1.0" UT 11:32 ND_LLSimaging/j1500 UT 11:58 OSU_monitor/M81 UT 12:18 OSU_monitor/N6503 UT 12:42 OSU_monitor/M82 penultimate red image had the too few downloaded pixels error penultimate red image may not be useful UT 13:00 Closing the dome UT 13:15 MODSCAL: grpixflats UT 13:36 MODSCAL: grpixflats_r
