Date: 2016 June 09 UT
Observers: P. Garnavich, T. Holland-Ashford, M. Fausnaugh
TO:  Geno B.
SA:  Barry R.

Summary: Mostly closed for clouds.  Completed two poor-condition MODS
          programs at beginning of night before closing for thick
          clouds.  Ran a bright target at end of night with lighter
          clouds, but well into twilight.

Completed programs:  OSU_AGN, OSU_ASASSN14li (thicker clouds) binocular MODS

Also observed UM_v339del, but well into morning twilight. MODS2 only

Calibrations: None.  Lamps and pixel flats were taken on
20160607 (director's time), can be used for this run (until we do
calib programs).
