Date: 2019 Apr 02 UTC Observers: Danielle Berg (driving) and Jack Neustadt TO: Steve Allanson SA: Barry Rothberg Moon phase: Waning Crescent/New moon (?) Summary: weather started out crummy, cloudy, but okay seeing cleared up, got some good seeing (sometimes <1") intermittent clouds towards end of the night running out of dark, priority, end of the night MODS targets!!!! (what a nice problem to have) Calibrations: LUCI: UM_XMDs/ArArc, NeArc, SpecFlats UVa_BCD_LUCI/Ne, flat+Ar UVa_MAKEMAKE/LUCI1_Flats_Arcs, LUCI2_Flats_Arcs Completed Programs: OSU_STORM/ngc4051, pg1411 OSU_redLSBGs/G635 OSU_BSGs/n4736f1 UVa_BCD_MODS/J1444b Standards: Feige 34 - dual, red-only+blue-only BD+332642 - dual, red-only+blue-only Details (All times UT): ---------------------------------- 00:?? - Starting with LUCI to run cals reran MAKEMAKE calibrations because, for whatever reason, they don't appear in the LUCI log from 3/30 put LUCI in safe mode 01:42 - starting up MODS 01:50 - began acquiring standard Feige34 (up to) 4 mags of extinction, variable clouds 02:31 - cleared up a bit, began acquiring feige34 again 02:40 - began observing Feige34 seeing somewhat improved, but extinction all over the place 03:05 - began acquiring OSU_dwarfs/DDO113 extinction too crappy - can't hone on guide star 03:21 - began acquring OSU_STORM/ngc4051 03:32 - began observing OSU_STORM/ngc4051 immediately lost right guide probe - stopped data re-ran acquisition scripts 03:47 - began observing OSU_STORM/ngc4051 (again) seeing around 1" according to dimm, but lots of intermittent clouds 04:18 - began acquiring OSU_redLSBGs/G635 had to switch to 3k x 3k images before aligning so that we could see both targets acquiring script only had us exposing with 1k x 1k (hmrph) able to see faint galaxy in bottom of slit 04:48 - began observing OSU_redLSBGs/G635 seeing around 0.8" (according to dimm) occasional clouds towards end, mostly clear 06:59 - began acquiring OSU_BSGs/n4736f1 07:15 - began observing OSU_BSGs/n4736f1 seeing around 0.7-0.8" relatively clear 09:29 - began aquiring UVa_BCD_MODS/J1444b 09:44 - began observing UVa_BCD_MODS/J1444b seeing around 1" obs program a bit strange - running 1x900s exposures 4 times 10:55 - began aquiring OSU_STORM/pg1411 11:03 - began observing OSU_STORM/pg1411 seeing around 0.9" intermittent clouds 11:35 - began acquiring standard BD+332642 some issue with pointing, but solved 11:46 - began observing standard BD+332642 mods1r temperature sensor read off multiple alerts, measurements that made no sense (+75 C, then -273 C) despite warnings, no (apparent) impact to data
