Institution(s): MDM

Instrument: OSMOS/B

Worked for 12 hours (all night)
Conditions were Mixed most of the night.

Observing Summary:

A decent night overall. Noticed a big (likely) spot of dust during
evening twilight. Will want to blow that off tomorrow.

Lost connection to the TCS. First noticed that the focus
wouldn't move, then that the MDM TCS Agent window said
the link was down. Closed and restarted all the telescope
control windows on the workstation and the TCS program 
and got back on sky relatively quickly.

Had to tighten the cam on the RA drive to stop the guide star
from drifting. Also a quick fix.
