Weather Conditions

Observing Plan and Goals for the Night

Install new hexapod LUT to validate before TCS engineering nights.
  1. Standard bias and dome flat sequence during afternoon (no more u band)
  2. Please try to get dome open for temperature equilibration at earliest appropriate time, be sure all cooling/ventilation systems are on.
Monitor Conditions:
  1. Make sure RASICAM is online if weather conditions permit.

Expectation for tonight is clear weather, decent seeing, tracking with modest ellipticity (<~0.1), poor tracking N of zenith.

Obstac should be configured to allow observations to X<1.5

Prioritization for tonight's observations:
  1. Photometric standards sequence as soon as dark enough (ugrizY in 3 fields at different airmasses, preferably one at X < 1.25, one at X = 1.25-1.65 and one at X > 1.65) and again at handover to Dara. Conditions: clear or thin clouds, any seeing.
  2. Filter donuts: 30s exposure 1500 um out of focus in filters gizY. Also take 1 r-band donut at each science pointing to confirm LUT. Conditions required: anything but thick clouds.
  3. Sky_Brightness_Measurements At fields from Paul. Conditions: clear, after twilight.
  4. Southern cluster fields: Full-depth izY(r) imaging on RXT 2248.7-4431, and El Gordo, at dec < -40. Conditions: clear or thin clouds, images <1.2"
  5. Bullet cluster: Complete last 2 pointings in rizY.
  6. DECal sweeps Conditions required: Any.
