Ops Comments	none

TO Comments	Cloud cover prevented observing for most of night. Trouble maintaining guiding on guide stars prevented even setting up much of the time. Down wind conditions at times.

RA Comments	Night devoted to sci with soem eng. Sky moderately cloudy at sunset. Took LRS2/VIRUS skyflats. Variable clouds during first half of night. DIMM was tracking Capella but could not get seeing measurements dues to clouds.
