MDM Observatory 2.4m Telescope Observer's Report for 2004 Jan 05

Observer(s): Patrick Cseresnjes
Institution(s): Columbia University

Instrument: 8K Camera

Worked for 12 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1.4 arcsec, Cirrus, Winds Calm
   Mid: Seeing 2.5 arcsec, Clear, Winds Calm
   End: Seeing 2 arcsec, Clear, Winds Calm

Observing Summary:

Could not make flats at the beginning of the night because of clouds. The 
sky then cleared up and the seeing was acceptable for 1-2 hours 
(~1.4 arcsec.). Data have been taken throughout the whole night in spite 
of a bad seeing (2-3 arcsec.) starting at ~9 pm.

A small problem: at the end of the night, the detcom refused to run any 
exposure. This has been fixed by switching off/on the power supply of the 
camera and restarting a new detcom session. The impact on the data 
collection was minor.
