Thompson Moon phase: Wanning Gibbous Summary: 6263006 Calibrations: Dual Grating Standard Feige 110 Dual Grating Standard G191B2B RV standard J06344388 Completed Programs: OSU_ASASSN/ASASSN19acc OSU_ASASSN/J05215658 OSU_ASASSN/ZTF19abvgxrq UM_V392/v392per OSU_LIGOEM/AT2019wxt OSU_ASASSN/J063923 ND_paloma/paloma UVa_FRAGN/J0832 UVa_FRAGN/J0751 OSU_STORM/mrk142 Details (All times UT): ---------------------------------- 00:30 - Getting things set up, planning to start with a standard star. 01:15 - Done with Feige 110 in dual grating, now going after ASASSN-19acc. 01:30 - Started ASASSN-19acc observations, looks like there's a small amount of cirrus overhead. 02:00 - Now going for J05215658. 02:30 - Finished previous target, going to ZTF19abvgxrq. Still light cirrus visible on the all 04:00 - Had to call Mark Wagner to get scripts for UM_V392, since they weren't in the OBs directory, but he replied promptly so it wasn't a big issue. Now going for that target. 05:00 - Moving to the potential GW-associated event triggered earlier today, AT 2019wxt. 06:15 - Finished the LIGO target, now getting the standard star G191B2B. 06:50 - Starting observations of J063923. 07:15 - Moving to RV standard J06344388 and unwinding the rotator. 07:50 - Moving to ND_paloma CV target. The 3rd image on mods2 may be compromised because there was a second bright star near the chosen guide star, which caused the guide software to jump between the two during the exposure. This only occured once during the observation, so even if that image is compromised the others should be fine. 10:45 - Hoping to get some UVA targets done. Starting with J0832. Had an echelle rip on MODS1 at the end, so we took one extra set of exposures to compensate. 11:30 - Now moving to J0751. A bit of clouds showed up as the exposure progressed. 12:10 - Attempted to go to J0800, but it got pretty cloudy. Going to try OSU_Storm/Mrk 142 instead. Clouds lightened up a bit during the back half of the observation.
