OSURC run UT 03 February 2017 Observers: Terndrup, Liss, Wiens Telops: Bechetti Staff observer: Rothberg Cloudy to start, so delayed opening. Cirrus floated by all night long, gradually improving through the night but never clear. UT 02:15 Completing calibration series for LUCI observations. luci1.20170203.0001 through 0005 Dark 600 sec UT 02:40 MODS calibration frames for special setups on previous nights. binned 2x1 bias frames (ND_polar program) image nuumbers 1-5 in all frames binned 2x1 slitless flats image numbers 6-10 red saturated 11-15 blue UG5 filter repeat with shorter exposures in red blue side images 16-20 red side images 11-15 3K red imaging flats red side images 16-20 ASASSN program UT 03:30 Opening to see whether we can do bright programs. UT 03:45 Setting up on ND_carbon target jy3321 04:00 Here a bit earlier than requested h.a. range, staring observations. Seeing is quite poor (1.2"+). Cirrus all over the sky. Will run obs files twice. mods1b.20170203.0021 through 0026 mods1r.20170203.0024 through 0029 mods2b.20170203.0021 through 0026 mods2r.20170203.0024 through 0229 Seeing has improved, and is now subarcsecond most of the time. UT 05:45 OSU_Algol: an unplanned test program (Terndrup) for poor conditions ... like now. mods1b.20170203.0027 through 0042 mods1r.20170203.0033 through 0048 mods2b.20170203.0027 through 0042 mods2r.20170203.0033 through 0048 UT 07:00 Acquiring and observing ASASSN-14ae. Running the ob scripts twice. mods1b.20170203.0043 through 0048 mods1r.20170203.0052 through 0057 mods2b.20170203.0043 through 0048 mods2r.20170203.0052 through 0057 UT 09:05 Acquiring ND_carbon jy2559. Using pa0 acq script. Did not find guide star on MODS1, and MODS2 had a shadow in the middle of the field. Geno is doing a pointing check and then we will rerun the acqusition. After checking the pointing (following a long move), all was well. 09:20 Started science OB for ND_carbon jy2559. Seeing is ~0.6". Do scripts twice. mods1b.20170203.0049 through 0054 mods1r.20170203.0061 through 0066 mods2b.20170203.0049 through 0054 mods2r.20170203.0064 through 0069 UT 10:40 Acquiring OSU ASASSN13bt. Another long move, and we did not find guide star on MODS1 again. Geno did another pointing check to resolve the issue. He estimates we were off by ~20". 11:02 Completed acquisition and beginning science OB. Seeing is now around 1". Run scripts twice (no other bright objects up). mods1b.20170203.0055 through 0060 mods1r.20170203.0070 through 0074 mods2b.20170203.0055 through 0060 mods2r.20170203.0074 through 0079 UT 13:45 Ended with standard gd 153
