Observing Summary:

I observed for some time without any problems. Then, during an exposure
Prospero froze. After trying a few things, I was able to continue
taking images. Then around 11 pm, I heard a strange grinding noise
coming from the dome. This happened twice, stopping before I could 
determine its source. Right after this, I began having
trouble with the guider. I would expose and no stars would appear.
Since it was not cloudy, I tried several diagnostics and determined
that the guide probe camera was either out of communication with the 
xmis, or something more serious was wrong. I tried quitting xmis(using the
drop down menu, not the x), but got an error when I tried to re-load
it. Since my exposures are long and need guiding, I decided to 
close down for the night around 2 am.
