MDM Trouble Report for 2006 Mar 21

Telescope: 2.4m
Observer(s): John Thorstensen (Dartmouth)
Instrument: Modspec + Echelle CCD

Problem(s) Encountered:
There's some pattern noise present in the images, easily 
visible on the background portions.  It looks as if there's
some kind of pickup, maybe 60 Hz.  Since the instrument is
coming off, there's no need to fix it right away, but it's 
something to watch out for when the echelle chip is used
the next time.
