Date: 2016 June 08 UT
Observers: P. Garnavich, T. Holland-Ashford, M. Fausnaugh
TO:  Geno B.
SA:  Barry R.

Summary: LBC with clear skies all night, some haze along horizon
(non-photometric conditions).  Seeing was variable, averaging near 1.0
arcseconds and oscillating around 0.9--1.3 arcseconds (sometimes
fluctuating above this, much better just before morning twilight).
Minor technical problem lost ~7 minutes.

Completed programs:
  LBC:
   OSU_monitor:  N3627SN, N4395, N4826, N4236, N4214, N4258, M101, N6946
   ND_ksn14gri,Uz, ND_ksn10Uz

Also observed OSU_monitor N6503, but technical glitch only gave 5/6 R
band exposures.  Observed ND_ksn10gri well into twilight.

Calibrations:
Biases, Skyflats with U-Spec, U-Bessel, BVR, and griz.

Details 
(all times UT, seeing estimated from science images, usually
the blue side):
------------------------------------------------------------------
02:12 -- Opened.  Skies clear, light haze, some clouds on horizon.

02:35 -- Skyflat test.  counts saturated.
02:53 -- Skyflats look good, running sequence:
      	 	  blue: U-spec B (OSU_monitor) and U-bessel g (ND_ksn)
                  red:  R (OSU_monitor)and riz (ND_ksn)

03:21 -- N3627SN focus (will collimate during twilight)
03:41 -- N3627SN observation ~0.9 arcsecond seeing
         plenty of signal to noise, focus is good, seeing is great

04:01 -- N4826 focus
04:07 -- 18 degree twilight
04:09 -- N4826 observation ~1.3 arcsecond seeing
04:35 -- seeing is degrading, ~1.5 arcseconds

04:47 -- focus field N4395
04:56 -- N4395 observing

05:14 -- ND_ksn15gri focusing
05:18 -- ND_ksn15gri observing ~1.1 arcsecond seeing
05:50 -- ND_ksn14Uz focusing
05:54 -- ND_ksn15Uz observing  ~1.0 arcsecond seeing

06:28 -- N4236 focus and copoint
06:41 -- N4236 observing, ~1.0 acrsecond seeing

06:55 -- N4214 focus
07:00 -- While running dofpia, had a few strange errors:
         1-- Time-out in dofpia terminal
	 2-- Something like multiple OBs trying to run in lbccontrol
         3-- In one pupil image, some pixels were missing.  
          Barry says this is a known problem, and causes 2 above.
07:04 -- N4214 observing, ~1.0 arcsecond seeing

07:13 -- N4258 focus
07:19 -- N4258 observing, ~1.1 arcsecond seeing

8:00 -- M101 focus
8:08 -- M101 observing, ~1.0 arcsecond seeing

8:35 -- N6503 focus
8:43 -- N6504 observing, ~1.0 arcsecond seeing
8:59 -- Last red side exposure stalled---lost this exposure (2/3 R band)

9:02 -- N6946 focus
9:08 -- N6946 observing, ~0.9 arcsecond seeing

9:44 -- ND_ksn10Uz focus
9:49 -- ND_ksn10Uz observing, ~0.8 arcsecond seeing
        red side collimation drifted for last 3 exposures (very bad by end)
10:16 --ND_ksn10gri focus
10:27 --ND_ksn10gri observing, ~0.6 arcsecond seeing (!!!, but red side only,
          blue has a slightly elongated PSF)
10:30 --18 degree twilight 

11:00 -- Redoing V band flat.

11:31 -- Closing, biases
