Observing Plan and Goals for the Night

  1. Afternoon calibrations script to use: prenight_calibration.json
  2. Start of night standards.
  3. Nightly out of focus image. script to use: defocus_nightly.json (right after last standard, no break)
  4. ObsTac.
  5. End of night standards.
  6. End of night calibrations. if start of night calibrations good use: postnight_calibration.json, otherwise use postnight_zeros_flats.json

Camera and Telescope
Telescope is on white spot and camera is ready to go.

Last Night's Data
WF and SN the night before.
Last night was very nice. WF z and Y-band with < 1" seeing.
Nightly out-of-focus images are working and will be done regularly.

Last night had to restart pipeline6, observer1, and readout1 machines
during calibrations.

Got last night's data and it is being processed already.
DQ is in hand for 11/18 and 11/19.

X1 from a couple nights ago (11/18) data quality failed seeing
and signal to noise for 2 of the filters => X1 needs to be redone.
Robert's version of the software flagged that as so. Robert produced
the DQ file and sent it to DES operations for implementation.

OBSTAC decides what to observe, including whether to do SN sequence.
SN would be happy to allow one image of a SN sequence to be bad but
still keep the sequence as good, but at present OBSTAC will flag the sequence
as bad if any of the images is labeled as bad. In tonight's case, since
2 filters of X1 were bad, everybody is happy with the result. E.N. will
work on OBSTAC in this regard but that will take some time.
Data bases going down starting on Friday afternoon. Will be able to
receive data but not process it during the interval.

Weather looks good.
We expect it to redo X1.
Otherwise g,r,i when the moon is down, i,z,Y when the Moon comes up.
