Summary

We observed with MODS from twilight until 10:45pm, at which point we turned the telescope over to LBTO for the 'middle half' of the night. These finished a little early, so we got the telescope back at 12:15pm and started with LBC. 

Seeing was about 1" through the night. Lots of clouds during the first half, 
while the second half seemed completely clear. 

MODS observations included a spectrophotometric standard, SN 2014ad, and 
LRG1134. LBC observations were all Monitor targets: N5194, M101, N6503, and 
N6946. We will take calibrations later.

The ventilation for the red mirror shut down around the middle of the night. 
We also experienced dofpia convergence issues on the red side, which may have 
been related. There was one mirror panic that led to about a half hour 
of lost time. Some other time was lost due to poor dofpia convergence. 

Details: All times are UTC unless otherwise indicated

Configured for MODS1 

02:10 - Shutter doors opened, there are still lots of clouds on the horizon.
	Waiting for clouds to clear. Temp is 14.4C. Humidity 20.5%. Winds 
	around 7 mph. Somewhat clearer to west. 

03:18 - Did Pointing Star. The AGW needed to be homed before we could find 
	the star. Still cloudy.

03:35 - acquire gd153 - dual grating

03:39 - start integration of gd153 dual grating calibration (0.9" seeing)

03:55 -	acquire sn14ad

04:08 -	start integration of SN 14ad (3 x 10 minutes) (1.1" seeing)

05:02 - start integration of lrg1134+2555 (3 x 10 minutes) (1" seeing)

05:43 - Handoff to Engineering team

Configured for LBC

07:15   Handover back from technical time, setup on N5194 for OSU_monitor. 
        Some problems with red side convergence due to ventilation problem.
 
07:30   Start N5194 OB, moon has set. Red side ventilation is off due to
        a stuck valve. Not a huge gradient, however, and image quality
        seems okay.
 
08:11   Setup on M101
 
08:18   Start M101
 
08:49   Setup on N6503
        Problem with red convergence, had to clear and restart dofpia
 
09:07   Start N6503
 
09:25   Setup on N6946
        Again problem with red convergence. Terminated dofpia manually.
 
09:35   Start on N6946
09:39   Aborted Exposure due to panic from right mirror.
 
09:48   Back to setup on N6946.
        Red did not converge. Z22 value doesn't change from -100.
 
10:04   Start on N6946; will go about 15 mins into Twilight.
