MDM Trouble Report for 2012 Apr 15

Telescope: 2.4m
Observer(s): Rebecca Santana (Ohio University)
Instrument: R4K OSMOS

Problem(s) Encountered:
Had the power flicker twice in the night, everything stayed on, and I
checked to make sure none of the breakers had been flipped.  Around 23:00,
a few of my exposures ended up the same as had happened on 4/12, where it
appeared as if I had taken a 10 min zero.  I'm not sure if the shutter didn't
open or what, but it was clearly not taking exposures.  I spent about an hour
trying changing targets and trying to figure out what was going on before it 
sort of fixed itself, continued with observations.  Also to note is that there
has been some odd shapes going around the aperture that don't match with a
blocked guide probe.
