LBT OSU/RC Observing Notes Date: 2016 Feb 10 (UT) Observers: Kevin Croxall (at Tucson Remote Facility) Support: Barry Rothberg TelOps: David Gonzalez Summary: Beautiful skies at sunset. Clear as can be. Winds rising a bit Not a single cloud on the radar map. Observed several more targets. Discovered the MOS mask for the SDSS1029 field was not in the instrument. This has already been scheduled to be loaded tomorrow. Completed science targets: UM_ASN15th OSU_KDdivBLRqsos/J0820_tellstar OSU_KDdivBLRqsos/J0820 OSU_KDdivBLRqsos/J0914_tellstar OSU_KDdivBLRqsos/J0914 OSU_KDdivBLRqsos/J0826_tellstar OSU_KDdivBLRqsos/J0826 OSU_KDdivBLRqsos/J0935_tellstar OSU_KDdivBLRqsos/J0935 OSU_KDdivBLRqsos/J1033_tellstar OSU_KDdivBLRqsos/J1033 UVa_BCD_MODS/J1220 OSU_KDdivBLRqsos/J1111_tellstar OSU_KDdivBLRqsos/J1111 _____________________________________________________________ UT 23:55 MODSCAL: doBias noticed biases have unique names UT 01:35 UM_ASN15th still slightly in twilight skybrightness ~16.31... too bright in acq images UT 02:06 began science integration. Grey time target... so started 20 before twilight, but added 1 20 min exposure to the .obs file. skybrightness ~21.34, seeing ~0.8" UT 03:335 OSU_KDdivBLRqsos/J0820_tellstar even with the ND1.5 filter and 0.1s exposure we had saturation of the telluric on the acq. May not be perfectly centered but did my best given everything saturated red spectrum saturated. Went to an exptime of 1s and reobserved UT 04:02 OSU_KDdivBLRqsos/J0820 seeing ~1" UT 05:01 OSU_SDSS1029A mask not loaded..... UT 05:08 OSU_KDdivBLRqsos/J0914_tellstar UT 05:24 OSU_KDdivBLRqsos/J0914 seeing ~1.1" UT 06:20 OSU_KDdivBLRqsos/J0826_tellstar Seeing ~0.99" UT 06:38 OSU_KDdivBLRqsos/J0826 seeing ~1" UT 07:34 OSU_KDdivBLRqsos/J0935_tellstar UT 07:51 OSU_KDdivBLRqsos/J0935 seeing ~1.1" RED GO command failed had to resend the preset UT 08:53 OSU_KDdivBLRqsos/J1033_tellstar seeing ~1.1" UT 09:10 OSU_KDdivBLRqsos/J1033 seeing ~1.5" UT 09:59 seeing ~1" UT 10:07 UVa_BCD_MODS/J1220 emission lines clearly present including 4363 UT 11:28 OSU_KDdivBLRqsos/J1111_tellstar UT 11:42 OSU_KDdivBLRqsos/J1111 seeing ~1" had to reacquire as the ROI on the acquisition image did not contain the target. Inreased to a 3kx3k acq. UT just before twilight... Hz44 UT 13:26 MODSCAL: imflats_r.cal UT 13:31 MODSCAL: slitflat_5as.cal UT 13:49 MODSCAL: slitflats_r.cal
