Date: 2018 Jun 18 (UT) Observers: Paul Martini, Emily Griffith, Jake Turner TO: David Gonzalez SA: Dave Thompson (on call) Moon phase: Dark Summary: Took some skyflats and completed 8 OSU_monitor targets. Had trouble focusing at the begining of the night since the telescope had been closed for 3 days. Sky was very clear all night. Calibrations: Sky flats UsBRV Completed Programs: OSU_monitor/NGC4449/LBC OSU_monitor/NGC4214/LBC OSU_monitor/NGC5194/LBC OSU_monitor/NGC4605/LBC OSU_monitor/M101/LBC OSU_monitor/N5474/LBC OSU_monitor/NGC6503/LBC OSU_monitor/NGC6946/LBC Details (All times UT): ---------------------------------- Plan: LBC all night 02:35 - sunset All clear except maybe a distant cloud or two 02:58 - sky no longer saturated, starting twilight flats in B, R, PA=-180 03:04 - PA = -90, 2s 03:08 - PA = 0, 4s all had >10,000 counts 03:16 - starting Us, V at PA=0, using 20s 03:45 - starting dohybrid near NGC4449 03:55 - dohybrid/dofpia went nonlinear, had to clear active optics and restart it 04:13 - co-pointing 04:15 - N4449 stopping, B image really bad 04:20 - redoing dohybrid 04:37 - dohybrid went nonlinear again, had to clear active optics and restart 04:50 - dohybrid went nonlinear again again, had to clear active optics and restart 04:59 - starting N4449 B image is slightly degrated (not perfect focus), red image is good! 05:18 - moving to N4605 05:24 - starting dofpia co-pointing 05:49 - starting N4605 06:05 - moving to N4214 and starting dofpia 06:13 - dofpia went nonlinear again, had to clear active optics and restart 06:37 - starting N4214 06:48 - moving to 5194 and starting dofpia 07:00 - starting N5194 07:40 - moving to M101 and starting dofpia 07:52 - starting M101 08:23 - moving to N5474 and starting dofpia 08:30 - starting N5474 09:06 - moving to N6503 and starting dofpia 09:18 - starting N6503 09:33 - moving to N6946 restart LBC control due to housekeeping error 09:39 - starting dofpia 09:48 - starting N6946 10:25 - finished for the night (astro twilight at 10:30)
