Observing Plan and Goals for the Night

  • Handover from community team
  • midnight standards [grizY ordered scripts]
UT Date = '2015/08/25 04:45'     Local time = 01:45
SDSSJ0200-0000        ra 02:00:00  dec +00:00:00  secz 2.1
SDSSJ0100-0000        ra 01:00:00  dec +00:00:00  secz 1.5
SDSSJ2140-0000        ra 21:40:00  dec +00:00:00  secz 1.2
  • Obstac until standards (clear) or 07:19 (cloudy)
  • morning standards (if clear) [grizY ordered scripts]
UT Date = '2015/08/25 10:05'     Local time = 07:05
SDSSJ0000-0000        ra 00:00:00  dec +00:00:00  secz 2.0

SDSSJ0320-0000        ra 03:20:00  dec +00:00:00  secz 1.2
  • Things to keep in mind:
    • Watch for opportunity to do ptc scan. "Opportunity"= dome closed at night.
    • defocus_nightly.json is suppose to be run weekly- it was run last night
      • According to Aaron, photometric conditions aren't important, but seeing should be below 1.2-1.3"

Notes from the 4PM Meeting

  • Last second SISPI problem during 1st half. SISPI lost the guider PAN. Reconfigured and
    restarting SISPI brought it back to life. 15 minutes of non-DES time was lost. It turns out this is a problem that is known from the past, but hasn't occurred for a while.
  • Klaus wrote: I restored the SVE code with the queue length telemetry I wrote a little test program to check network latencies
    outside of SISPI. This will be running to night.

Other Notes
