MDM Trouble Report for 2009 Feb 26

Telescope: 2.4m
Observer(s): Thomas Brink & Brad Tucker  (University of Michigan & ANO)
Instrument: 8K

Problem(s) Encountered:
At the very end of the night, while taking twilight flats, we 
encountered a minor error.  We tried to initiate an exposure in 
the detcom window with the  go  command, but before the exposure 
began an error message appeared in the detcom window stating: 
 Filter expected to be in position I (slot 4) but sensed in slot 
0.  Please issue new filter command confirming which position you 
want.   We issued the command  filter 4 I , and tried the 
exposure again, but a similar, shorter, filter error message 
appeared.  This message appeared once more.  We're not sure what 
caused this message to appear, or disappear.
