MDM Trouble Report for 2007 Nov 24

Telescope: 2.4m
Observer(s): Assef & Atlee (OSU)
Instrument: Retrocam

Problem(s) Encountered:
The strange patterns which appeared in the z-band images recorded
with Retrocam last night have recurred.  Unlike last night, we
did not run out of cryogen at the end of the night, possibly due
the poor weather conditions, as our late start allowed us to top
off the Nitrogen reservoir part way through the night.  We can
therefore rule out any consequences of a warming instrument.
Also, the pattern does not appear to have changed from last night,
which makes it unlikely that condensation appeared on the filter,
since the humidity tonight was much lower.
