Observing Plan and Goals for the Night

  1. New version of FCM - bug fixes.
  2. Standard bias and dome flat sequence during afternoon.
  3. Dome open for temperature equilibration at earliest appropriate time
Prioritization for tonight's observations:
  1. Standard stars if photometric, which appears unlikely.
  2. ObsTac DES survey and SN fields (if any)
  3. Repeat bad SN fields (C3 g-band), by marking these bad. Test this procedure.
  4. Monitor pointing and offseting behavior during SN observations.
  5. Morning standards, if photometric

Notes from the 4PM Meeting and Additional Comments:

  1. Discussed procedure for marking exposures bad. Decided we'll try repeating at least the bad SN observations (C3 g-band)
