Observer Support: 
Hernan Tirado
Night Assistant: 
None
Also Present: 
Alex Drlica-Wagner, David James, Claudia Belardi; Daytime Humberto Orrego
Problems: 

Observer1 crashed hard (screens froze; no response to a ping) just as afternoon calibrations were ending, defeating an attempts at running darks.  A reboot by telops brought it back to life.  SISPI stayed running.

2nd Half: none

DES Observers: Steve Kent, Alex Drlica-Wagner
Telops: Humberto Orrego, Hernan Tirado
Remote Support: Klaus Honscheid

Observing Plan

Half-night plan

  1. standard bias and dome flat sequence
  2. Darks
  3. evening standard stars
  4. Try to get SN-X3z to load in obstac
  5. Nightly defocus
  6. run ObsTac queue
  7. middle of the night standard star
  8. 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 arcsec at start; much of night around 0.75 arcsec
  5. Wind conditions: 6 mph
  6. Humidity: 50

Accomplishments

  1. Afternoon: zeros, dome flats (ugriz)
  2. No darks due to crash of observer1
  3. Klaus tested new guider code in anticipation of engineering nights. Seemed to work.
  1. Evening: Standards:

    • SDSSJ0200
  2. SN exposures – Attempt to get obtac to select SN-X3z – GLORIOUS SUCCESS!

    • SN-X3z
  3. Survey Exposures: 93 total
  4. Middle of night:

    • Standard SDSSJ1227
    • Standard SDSSJ1048
    • Standard SDSSJ0933
  5. Nightly defocus – readout occurs during handover to the Sooners. Hyperthreaded observing!

Problems tagged as Synopsis_Problem

  1. Just as afternoon calibrations were ending, observer1 died hard (no response to network ping.) SISPI itself was fine. The magic fingers of Humberto brought it back to life. No problems during the night.

 

Minor Problems and Relevant Information

  1. Occlusion alarms: 9
  2. Shutter errors: 0

Notes for Data Management

  1. Ignore exposure 282896 (test exposure by Klaus)
  2. Ignore exposure 282905 (pointing – no useful data)
