Also Present: 
Alex Drlica-Wagner, David James, Claudia Belardi
Problems: 

Afternoon reboot of SISPI hung; required a reboot of some computers.  Assistance from Klaus Honscheid, Jim Hughes, and Esteban Parkes brought things back to life.

2nd Half:
 
Restarted OCS twice  because it crashed for an unknown reason, then we reconfigured. It crashed a third time so we restarted SISPI. When this did not resolve the problem, we restarted SISPI a second time which did not fix the problem. Every time we attmpt to take an expsure we get an error saying OCS is broken.

Observing Plan

Half-night plan

  1. standard bias and dome flat sequence
  2. PTC sequence
  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 overhead; few clouds over ocean; no haze. Clouds seems to dissolve as the pass over land. Green flash sighted.
  2. weather during night: 22:00 pm (local): Clear
  3. weather during night: 12am (local): Clear
  4. Seeing conditions: 0.8-1.1 arcsec, depending on band and airmass
  5. Wind conditions: 5 mph
  6. Humidity: 25

Accomplishments

  1. Afternoon: zeros (281910-281918 and 281994-281997), dome flats (ugriz) (281919-281993)
  2. Never attempted PTC
  3. Evening: Standards:

    • E4-A
    • E1-A
    • SDSSJ0320
  4. Nightly defocus
  5. SN exposures

    • SN-S2 – We are pratically pointed at the moon!
    • SN-C3g,r
  6. Survey Exposures: 102 total – new record for this run!
  7. Middle of night:

    • Standard SDSSJ1227

Problems tagged as Synopsis_Problem

  1. First 2 attempts at dome flats failed (incomplete frames), third restart of SISPI hung. With help from snowed-in Klaus, Jim Hughes, and Esteban Parkes, we came back online. Worked flawlessly during the night.

Minor Problems and Relevant Information

  1. GPS was cleaned (not that it needed much)
  2. Occlusions alarms: 7

Notes for Data Management

  1. Ignore exposures 281887-281906 – Failed dome flats*Observing Team*
