Notes from 4pm meeting¶
Run Manager's Meeting January 24, 2017

HTD, David F., Bobby B., Rick K., Eric N., Doug T.,
Eric M, Josh, Manuel, Daniel
Camera & Telescope
------------------
Observers see there is a SISPI.
Camera is fine. Work going on in the dome.
Flats at 5:30.
Last Night
----------
http://des-ops.fnal.gov:8080/nightsum/nightsum-2017-01-23/nightsum.html
Never opened.
DECal fine scan of g-band. However one or more of the lamps seems to be poorly aligned
and the screen is not uniformly illuminated.
DESDM & DQ
-----------
No problems processing or downloading stuff in past few nights.
Forecast
--------
Partly cloudy now. Prediction is for it to clear up.
Deadman 7: C2, C3z, S1, S2, X3g
Deadman 6: C3r, C3i, X3z
Expect the SN fields on deadman 7.
Then WF tiling 6 mixed, then dark
AOB

SN discussion
SN Ramp Down Plan SN Group (Request)
1) Drop E fields after one more epoch (previous epoch was Jan 18, 19)
2) Take S and X fields off deadman on Feb 1 (may still be observed with seeing trigger)
3) Raise C field deadman to 9 days on Feb 1
Comments on request:
Recollection is airmass limit must be 2 to get the C-fields in mid-Feb.
Check in 2/9 to 2/14 break whether to enable C-fields any more on deadman.
Eric N is running simulations
Eric N has a separate deep and shallow field global deadman.
Plan for now:
run for now with airmass limits at 1.7
Json scripts to control when SN deadman occur.
Standard Stars:
All SDSS SS fields for next few nights.
Wildlife report: lizard.
WoD: argh.
