Observing log for UT 2011/02/11

Observers: Jeff Blackburne (OSU), Jill Gerke (OSU)

Observing Assistent: Geno Bechetti
Support Astronomer: Dave Thompson (from Tuscon)
Instrumentation: Doug Officer

Instrument: LBC-Blue

Conditions: At sunset, clear with some haze on the horizon, winds
~10m/s, humidity ~10%. About the same all night.

Seeing: 0.6'' to 1.8''

Programs: 
UVa_And -- one OB done, in B band.

OSU_monitor -- 12 targets observed.

ND_oldsn -- completed

OSU_wl -- one OB done, but the seeing was not as good as we had
hoped. We think the wind might have had something to do with it; we
were pointed straight into it.
