SA:  Barry R.

Moon phase: 1st quarter

Summary: Overcast at sunset with threatening clouds.  Conditions
improved and we opened 3 hours after sunset, but an issue with the
left guider delayed us another hour.  Skies were clear for the rest of
the night with some cirrus and variable seeing (0.7--1.5 arcseconds).

Completed Programs (Binocular MODS): UM_Novae/v5593sgr, ND_nher91a,
OSU_ASASSN-15qi (18 degree twilight), BD284211 (standard star, 12
degree twilight)

Details (All times UT):
-----------------------------------------------------------------
Plan is Binocular MODS all night
01:04 -- MODS waked.  Some trouble shooting on right side rotator
01:34 -- Issue is resolved.  Threatening clouds on horizon.

Sunset -- Overcast, (threatening clouds to the east).

03:45 -- Conditions improving

05:10 -- Opening
05:30 -- Issue with left side guider (no image)

06:20 -- issue is fixed, collimating (left side is slow)

06:31 -- collimated, moving to new target
      	 Acquiring UM_Novae/v5593sgr
06:49 -- observing v5593, seeing ~1.3 arcseconds (guider)
07:27 -- seeing spiked to 2.0 arcseconds at 900s into exposure
         Down to 1.75 arcseconds for exposure 3

07:55 -- Acquiring ND_nher91
08:08 -- Observing ND_nher91, seeing ~ 0.8 arcseconds
09:09 -- Variable transparency (guide star dimming), very variable seeing
      	  (fluctuating between 1.0 and 1.4 arcseconds)

10:15 -- Acquiring OSU_ASASSN-15qi
      	 sent manual offset, -0.3 arcseconds to MODS1 +0.3 arcseconds to MODS2
	 no through image because twilight is fast approaching
10:30 -- 18 degree twilight
10:33 -- Observing 15qi, seeing ~0.75
11:08 -- 12 degree twilight

11:11 -- Acquiring BD284211
