-01 First APOGEE Commissioning Night, Mar. 17, 2017 -01 Observers: Majewski, Almeida, Lane, Fuentes, Gonzalez (telescope operator) -01 Support: Sanchez-Gallego, Davidson, Holtzman (remotely) -01 Instrument focus set at +1700 (we expect this to be the final best focus) 001 60 Darks dither A 002 3 QuartzFlats dither A 003 20 ArcLamps (ThArNe) dither A -Communication failure during cal script while we were at dinner -This left the shutter open and the ThArNe lamp on -Therefore, chip had ThArNe light shining on it for ~1.5 hours 004 60 Darks dither A (aborted after ~10 darks after we realised comms failure) 005 3 QuartzFlats dither A (aborted due to comms failure) 006 50 Darks dither A (useful for testing latency from ThArNe lamp) 007 50 Darks dither A (useful for testing latency from ThArNe lamp) 008 50 Darks dither A (useful for testing latency from ThArNe lamp) 009 50 Darks dither A (useful for testing latency from ThArNe lamp) 010 50 Darks dither A (useful for testing latency from ThArNe lamp) 011 Science frame dither A (Magellan seeing ~0.6, guider RMS~0.3, airmass~1.1) 012 Science frame dither B (changed tracking rate from 15.000 to 15.005"/s after tracking test) 013 Science frame dither B 014 Science frame dither A 015 Science frame dither A 016 Science frame dither B 017 Science frame dither B 018 Science frame dither A 019 Offset sky (+60" in RA) dither A (for LSF test) 020 Offset sky (+60" in dec) dither B (for LSF test) 021 Science frame dither B (Magellan seeing ~1.3, guider RMS~0.5, airmass~1.3) 022 Science frame dither A 023 Science frame dither A 024 Science frame dither B (some small fluffy clouds) 025 Science frame dither B (some small fluffy clouds) 026 Science frame dither A (some small fluffy clouds) 027 Science frame dither A (some small fluffy clouds) 028 Science frame dither B (some small fluffy clouds) 029 Dome flat dither A -Now we are starting the dither test (2*ABBA+2*AAAA) to see if we can tell the difference between dithered and undithered observations 030 Science frame dither A (Magellan seeing ~0.8, guider RMS~0.3, airmass~1.1, some small fluffy clouds) 031 Science frame dither B (some small fluffy clouds) 032 Science frame dither B (some small fluffy clouds) 033 Science frame dither A (some small fluffy clouds) 034 Science frame dither A (some small fluffy clouds) 035 Science frame dither B (some small fluffy clouds) 036 Science frame dither B (cloud getting worse) 037 Science frame dither A (cloud getting worse) 038 Science frame dither A (closing due to cloud)
