MDM Observatory 1.3m Telescope Observing Report for 2009 Jan 29

Observer(s): Tom Brink
Institution(s): University of Michigan

Instrument: 4K

Worked for 9 hours (most of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Winds all night.
   Beg: Seeing 1.2 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Clear, Winds High
   End: Patchy Clouds, Winds High

Observing Summary:

Beginning and middle of the right were very good.  Winds of 20-25 
mph (gusts ~30-35 mph) made it impossible to acquire usable data
during the final 4 hours due to wind shake.  Unfortunately this 
was true at all pointings/azimuths, not just when pointed towards
the wind.

When guiding, the command tx paddle gain=0.02 no longer seems to
work.  The guide star quickly jumps out of the box.  Setting the
gain to 0.01 works however.
