MDM Trouble Report for 2022 Apr 01

Telescope: 2.4m
Observer(s): Laura Kay & Ed Moran (Barnard)
Instrument: CCDS

Problem(s) Encountered:
TCS issues from the previous night continued -- strange, because
all was fine at the end of last night.  We were able to move the
telescope a little east for twilight flats, but afterwards the
TCS was unresponsive.  Luckily we were not far from zenith so we
restarted the software.  Everything worked perfectly after that.

Almost.  The guider had huge errors on one axis, as if the wrong
rotation was set in Settings.  So, we restarted MaximDL, and
guiding was perfect after that.  Maybe the two problems were
related.

Strange ghost images still present in internal flat and Ar lamp
images. They are absent (or extremely faint) in exposures of
bright things (standard stars) and the twilight sky.

(Also the sink in dorm room 4 is leaking a lot)
