Date: 2016 June 14 UT
Observers: P. Garnavich,  M. Fausnaugh, J. Zinn
TO:  Geno B.
SA:  Barry R.

Moon phase: 1st quarter + 2 days

Summary: After a windy afternoon/evening, we opened to clear
skies---conditions were photometric all night.  Seeing was poor to
start (~2.0 arcseconds), but targets were low elevation (30--40
degrees).  Conditions improved to sub-arcsecond seeing near 7 UT,
which initiated the LUCI AO override.  Telescope was handed back with
MODS at 10 UT, we did one early morning target through twilight in 0.7
arcsecond seeing.

Completed Programs (Binocular MODS): OSU_ASASSN-15uh, OSU_ASASSN-16fp

Also observed: 8/18 UM_V2468cyg exposures---LUCI AO override
interupted this program.


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

02:30 -- Opened shortly before sunset, sky is totally clear. Wind is
      	 somewhat high (10 m/s).

03:06 -- Collimating.  Wind speed has dropped to normal levels.

03:11 -- Acquiring Hz44 (standard star).  Will do an i band and r band
      	 image to test MODS1 vs MODS2 red channel counts (at Rick Pogge's
	 request).
03:30 -- Observing Hz44 (just before 12 degree twilight).  
      	 Seeing ~ 1.0 arcseconds

03:43 -- Acquiring ASASSN-15uh
         Need to repoint (missing star on SX)
03:51 -- re- Acquiring ASASSN-15uh
04:04 -- Observing 15uh, seeing ~ 1.3 (GCS)
04:08 -- 18 degree twilight
         exposure 1:  Seeing is rising, average at 1.5 arcseconds (GCS)
	 exposure 2:  Seeing ~1.5 arcseconds (GCS)
	 exposure 3:  Seeing ~1.5 arcseconds (GCS) (32 degree elevation)

05:20 -- Acquiring UM_V2468cyg
      	 Recollimating at slightly higher elevation
05:44 -- grlamps and grlamps_mods2.  Changed these to the 0.8 arcsecond 
         slit so that the slitmask doesn't move.
05:58 -- when we went back to obsmode, the guide star was gone.
         Re-running acquisition script.
	 gave MODS2 a 1.5 pixel shift right (0.18 arcsecodns)
06:10 -- Observing UM_V2468  seeing ~ 2.3 arcseconds (GCS)
      	 DIMM is 1.3 arcsecond seeing, 
         DX occasionally fluctuates to 1.2 arcseconds (300s in 1st exposure)
06:43 -- End of exposure 3:  
      	     DX seeing is 1.1 arcseconds (GCS guiding average)	 
	     SX seeing is improving (2.0 arcseconds, fluctuating down to 1.1)
	     DIMM seeing is 1.2
	     (we think it is elevation---started near 40 degrees, now at 51)
07:01 -- Beginning of exposure 6: DX ~1.0 arcseconds, SX ~ 1.5 arcseconds
      	     DIMM ~ 1.2 arcseconds
07:27 -- Started second block.  Seeing is 0.8 arcseconds DX, 1.0 arcseconds SX.
      	 LUCI AO override is a possibility
07:50 -- LUCI AO in effect, we are letting this exposure finish (30 sec to go)
         Got 8/18 exposures.  Seeing is 0.6 to 0.8 arcseconds.


10:05 -- Pointing and collimating on MODS
10:18 -- Acquiring OSU_ASASSN16fp
10:32 -- Observing 16fp, seeing ~0.7 arcseconds (GCS)
10:33 -- 18 degree twilight

11:28 -- Closing
