Weather Conditions

*Tololo Weather Links Variable cloud cover. It might get clearer as the night goes on.

Observing Plan and Goals for the Night

  1. Standard bias and dome flat sequence during afternoon.
  2. Restart SISPI instance to obtain new ObsTac version.
  3. Dome open for temperature equilibration at earliest appropriate time
Prioritization for tonight's observations:
  1. Standard stars if photometric.
  2. ObsTac. Monitor if exposures with RA < 0 are completely absent.
  3. Repeat main survey exposures marked bad.
  4. Monitor pointing and offseting behavior during SN observations.
  5. Morning standards, if photometric

Notes from the 4PM Meeting and Additional Comments:

  1. Monitor CCD temperature telemetry.
  2. Monitor SN offsets more closely.
  3. Monitor ObsTac.
  4. Obstac would start off with wide field Y-band until 3 SN deep fields come up
    because of deadman. Expect 20" accumulated bad pointing
