Date: 2016 Nov 20 UT
Observers: M Fausnaugh, S Johnson
TO:  Steve A.
SA:  Olga K.

Moon phase:  5.5 days after full

Summary: Beginning of the night had great conditions besides a few
cirrus clouds passing through. Followed by a two hour interruption by
clouds. After reopening, light cirrus clouds that eventually
dissapeared. We ran into some technical difficulties with the remote
client which caused some lost time.

Details (All times UT): 
----------------------------------
Plan:  Binocular MODS all night.

23:40 -- (11/19) MODS started up, ready to run MOS calibs (UVa_perseus)

23:54 -- Uva_PerseusUCDs1.cal
      	 mods2r.20161120.0004 has saturation issue Ne+HG+AR

00:17 -- Opened.  Sky is hazy, clouds on the horizon.
00:54 --  mods1 guider issue, 

01:07 -- acquiring MODSPhotCal/feige110
01:11 -- observing MODSPhotCal/feige110
      	 -- high cirrus clouds
      	 -- seeing stable around 0.8''

01:24 -- acquiring OSU_DES/Z65QSO
      	 -- faint in through-slit image
01:44 -- observing OSU_DES/Z65QSO
      	 -- light, variable cirrus clouds
	 -- seeing stable around 0.7''
	 -- skies have cleared by exp 2

03:15 -- acquiring OSU_ASSASN/AT2016bry
      	 -- had to re-point
	 -- hard to see in through-slit, especially MODS2
03:37 -- observing OSU_ASSASN/AT2016bry
      	 -- seeing jumping around 1.3''
	 -- skies clear upon acquiring	 
	 -- some technical difficulties, name for first set of images
            on MODS2 are 16114M8.03m for BLUE and 161008M8.0nz for RED
	    -- could just be duplicate images though
	 -- had to restart observation at 04:19 due to obs3 crash from NXclient stuff
	    -- lost approximately a max of 15 minutes
	    -- restarted .obs script, but aborted after two exposures

04:57 -- acquiring OSU_ASASSN/AT2016eqa
      	 -- potentially wrong guide star, but will be fine
	 -- had to unwrap rotators, delayed a few minutes
05:18 -- observing OSU_ASASSN/AT2016eqa
      	 -- seeing steady at 0.55''
	 -- very minor cirrus clouds
	 -- ~06:11, seeing around  0.7''
	 -- moonrise at 06:23

06:57 -- acquiring UVa_PerseusUCDs/PerseusUCDs1
      	 -- clouds moving in fast
	 -- 07:03 lost guide star due to clouds

07:10 -- closed due to clouds

09:17 -- reopened once clouds cleared, some still on horizons

09:39 -- acquiring OSU_ASASSN/ASASSN16du
09:54 -- observing OSU_ASASSN/ASASSN16du
      	 -- seeing varying around 0.80''
	 -- clouds on horizon, might be an issue
10:25	 -- clouds moving in hard, beginning to lose guide stars, seeing up to 1.3''
11:06	 -- clouds moving away from target, seeing fluctuating arounbd  0.9''
11:25 -- observing OSU_ASASSN/ASASSN16du again
      	 -- clouds dissappearing, seeing around 0.7''
11:45	 -- high cirrus moving in a bit
	 -- cut third observation short on MODS1, twilight approaching


12:30 -- acquiring MODSPhotCal/feige34
12:43 -- observing MODSPhotCal/feige34
      	 -- seeing around 0.6''
	 -- cloudless sky
12:40 	 -- (-18degree) twilight
