MDM Observatory 1.3m Telescope Observer's Report for 2002 Oct 23

Observer(s): A. Stutz
Institution(s): OSU

Instrument: 8K

No Observing (see comments below)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds from 7PM until 11PM.

Observing Summary:


After taking some bias frames I noticed that the dewar was not
at the right presure, so I refilled it.  After that it returned tto
the normal presure (.3mT) 
Then clouds rolled in, and I had to stop. Humidity was high.  
While it was cloudy, Jen ran some tests on dome flats.  While one
of the exposures was reading out there was a software error:
   High voltage not enabled at utility board for 1st
                                                 2nd
Then, after spewing out this error a few times, the problem seemed
to go away, ie, the software gave no more errors.
However, every exposure after this was over-exposed.  
A 30 sec R_tj M31 image had a mean of 25000, instead on a mean
around 4000.
Not knowing what was going on, I stoped observing.
