Observing Plan and Goals for the Night

  1. Standard bias and dome flat sequence during afternoon.
  2. 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.
  3. Repeat main survey exposure marked bad (mostly from night starting 01/09)
  4. Monitor pointing and offseting behavior during SN observations.
  5. Morning standards, if photometric

Notes from the 4PM Meeting and Additional Comments:

  1. Eric Neilsen sent a list of exposures that we can mark bad based on QR seeing fwhm.
  2. If we get a more complete list of bad exposures from DM, we will use this, otherwise we'll just use Eric's list.
