Observing Plan

Half-night plan

  1. standard bias and dome flat sequence
  2. Darks
  3. evening standard stars
  4. Nightly defocus
  5. run ObsTac queue
  6. middle of the night standard star
  7. handover to community observers

 

Conditions

  1. weather after dinner: 7pm (local): Clear slight haze.
  2. weather during night: 22:00 pm (local): Clear
  3. weather during night: 12am (local): Clear
  4. Seeing conditions: 1.2 arcsec at start; 2nd half of night around 0.9 arcsec
  5. Wind conditions: 12 mph
  6. Humidity: 50

Accomplishments

  1. Afternoon: zeros, dome flats (ugriz)
  2. Darks
  3. Early evening test of pscjob
  4. Evening: Standards:

    • SDSSJ0200
    • C26202/HST
    • SDSSJ0843
  5. Nightly defocus
  6. SN exposures

    • SN-S1
    • SN-E1
    • SN-X2
    • SN-X3
    • SN-C3
  7. Survey Exposures: 70 total
  8. Middle of night:

    • Standard SDSSJ1227

Problems tagged as Synopsis_Problem

  1. DTS seems to have died starting with exposure 283439 (IB Error calling dtsq (Command: /bits/bin/postproc, Queue: des). Retcode: 1)

 

Minor Problems and Relevant Information #Pointing exposure had wrong prop-id

  1. Occlusion alarms: 6 (283406 big but nothing seen)
  2. Shutter errors: 0

 

Notes for Data Management

  1. Ignore exposures 283301- 283321 (darks)
  2. Ignore 283322 (test)
