Weather Conditions

  • Clouds on the horizon, and thin clouds overhead.

Observing Plan and Goals for the Night

No dome flats today; the camera temperature will not be stabilized in time. Will run standards and then Obstac.

  • Evening standards (using calspec):
UT Date = '2016/12/16 00:30'     Local time = 21:30
SDSSJ2140-0000        ra 21:40:00  dec +00:00:00  secz 2.1
Feige110_CCD_52       ra 23:19:58  dec -05:04:57  secz 1.3
SDSSJ0100-0000        ra 01:00:00  dec +00:00:00  secz 1.2
  • Obstac -- Will let obstac do its thing (which will include a lot of supernova).
  • Morning standards (using calspec):
UT Date = '2016/12/16 08:24'     Local time = 05:24
SDSSJ1227-0000        ra 12:27:00  dec +00:00:00  secz 1.7

Notes from 4pm Meeting

There will be lots of supernova tonight. The camera is cooling down, and will be ready to take data tonight.
