INAF LBC+LUCIFER queue observing, 2010 April11-12

Observer: R. Speziali, K.Boutsia
Telescope Operator: D.Gonzales Huerta
Support Astronomer: D. Thompson
Instrument: LUCIFER1

Summary

Clear night with thin cirrus at the beginning. The seeing was ~1.0.
Lost 30min during MOS acquisition because Skycat fails to load new images.
At 09:40 (UT) rotator hits a limit. David G.H. had to go to the dome and fix it.
At 10:05 (UT) the dome is closed due to strong winds.
