MDM Observatory 2.4m Telescope Observer's Report for 2001 May 29

Observer(s): Don Neill
Institution(s): Columbia

Instrument: 8K 

Worked for 8.5 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the summary for details.

Seeing and Weather:
   Beg: Seeing 2.0 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.5 arcsec, Cirrus, Winds Calm
   End: Seeing 1.0 arcsec, Clear, Winds Calm

Observing Summary:

Had a problem with dark slide on 8K not being secure and sliding
shut upon long slew.  Fixed by jamming (lightly) to one side to
stick.

Shutter stopped working during a focus run producing strange images.
We reset to zenith pointing and commanded the shutter to open and
close a few times.  The shutter worked fine after that.

Computer mdm1 froze after reading out 97% of last sky flat (lost).  
Had to reboot mdm1.  Once back up, communication with ccd was
restored and I continued with pof and turning off slave then
master power supply.  Seems ok now.
