INAF queue observing, 2013 April 4 - April 5

Observer: E. Sani, M. Faccini, A. Bongiorno
Telescope Operator: D. Gonzales Huerta
Support Astronomer: M. Edwards
Instrument: LBC

Summary

At the beginning of the twilight we have a completely cloudy sky. The dome remains closed due to rain risk.
Forecasts for the night foreseen bad seeing and partly cloudy, we thus require to use MODS. The crew is using the dome-closed time to replace the BCU grating and run tests for M2.
At the beginning of scientific operations we have low wind, 20% humidity with thick stratified clouds.
