Moon phase: Waning Cresent 

Summary:

No observing, completely overcast with thick high-elevation haze from the
California fires all night.  We could not see the Sun at sunset, but later
could see the Moon, so it had thinned some by then, but never saw more than
a couple of stars faintly.  Spent the night getting a very thorough set
of MODS calibrations.


Calibrations: 

Did all the MODS closed-dome calibrations we would need for the run, including
the 1x2 and 2x2 binning mode calibrations for ND_lamost and UM_wd when we
hopefully execute those programs, and cals for all 3 MOS masks for OSU_CHAOS.


Completed Programs: 

Calibration program crushed
