MDM Trouble Report for 2012 Apr 2

Telescope: 1.3m
Observer(s): Price-Whelan & De Rosa (Columbia University, OSU)
Instrument: CCDS

Problem(s) Encountered:
At the beginning of the night, we noticed the flats had a lot of 
structure that was not present in previous nights. After talking
to Kate Grier, we think it is condensation due to the CCD warming
up last night. The brightest point seems to be directly in the 
center of the CCD, so we moved the targets northward on the slit
and observed as normal. I took another set of dome flats at the
end of night to compare to the beginning of night flats.
