Weather Conditions

*Tololo Weather Links Clear + cold

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.
  2. Make sure obstac keeps filling queue and SISPI keeps loading exposures.
  3. Monitor pointing and offseting behavior during SN observations.
  4. Morning standards, if photometric

Notes from the 4PM Meeting and Additional Comments:
  1. Monitor ObsTac.
    Expect lots of y-band because the Moon is right in the face the first half
    of night. Later i and z, and SN fields if seeing is bad.
