MDM Trouble Report for 2003 Apr 28

Telescope: 2.4m
Observer(s): Bjork, Paust (Dartmouth)
Instrument: Echelle

Problem(s) Encountered:
CCDcom reported errors when trying to read out images.  For a while around 5 UT, this occured every three images or so and caused us to lose a number of long exposures.

 ccd_aread: wrong aio finished; expected 0.  This is bad. 

We were able to get the camera working again by redownloading the camera's code and reinitializing the utility board.

In the morning while refilling the dewer, there was also a buzzing noise coming from either the camera or the filter wheel.  Initializing the xmis made the noise stop.
