INAF queue observing, 2013 May 9-10

Observer: F. Cusano, R. Speziali
Telescope Operator: S. Allanson
Support Astronomer: O. Kuhn
Instrument: LBC -MODS

Summary

In the afternoon snow, at the sunset clouds covering 50% of the sky.
At the beginning of the night during the LBC observations the sky was higly variable, with cirrus and clouds passing through.
We switch to MODS to collimate the secondary and try to observe Sommariva. Collimation not reached.
At 09:00 UT the sky is clear and we start observing with LBC.
