Observers: Michael Fausnaugh SA: Olga K. TO: Geno B. 1/2 night split with Pathfinder. MODS + LBC, hand over ~06:55UT Clouds have moved out, weather is clear. Light cirrus clouds toward the end of the night MODS UM_N2403_star (x2) LBC OSU_monitor: N2403, N4449,N3489,N4736,N4826, M101 detail (all time UT) 07:12 acquisition UM_N2403_Stars 07:21 observing UM_N2403 (seeing ~1.1) After checking first exposure, found that the blind offset did not send (observer's error). Blind offset and updatepointing sent in MODS GUI command line. 07:44 observing UM_N2403 (seeing ~1.2) (use data starting at mods1r.20131211.0005.fits) 08:20 observing UM_N2403 (seeing ~1.2) 08:56 running N2403_star_Ar.cal 09:01 TO said that the telescope did not stop tracking, re-ran N2403_star_Ar.cal 09:05 On SA's suggestion, re-ran N2403_star_Ar.cal with a 0.6 arcsecond slit 09:08 Re-configuring for LBC 09:36 OSU_Monitor/N2403 co-pointing 09:52 applied AO correction manually, rerunning dofpia 10:01 observing N2403 (seeing ~1.1) 10:10 focus OSU_Monitor/N4449 10:16 observing N4449 (seeing ~1.0) 10:28 focus OSU_Monitor/N3489 Had a problem with the lbcrangebal, looks like there is a slight offset 10:40 observing N3489 (seeing ~1.0) Patchy, thin cirrus clouds 11:19 focus OSU_monitor/N4736 11:26 observing N4736 (seeing ~1.1) More cirrus clouds, seeing is a little jumpy (up to 1.3) 11:42 focus OSU_monitor/N4826 11:49 observing N4826 (seeing ~1.0) light cirrus clouds loosing focus in last 2 exposures on blue side 12:28 Focus OSU_monitor/M101 12:34 observing M101 (seeing ~1.1) Last 3 exposures (on each side) pushed into twilight, last one is probably un-usable (UT ~13)
