MDM Trouble Report for 2008 Jan 26

Telescope: 2.4m
Observer(s): Statler, Riethmiller, Cotto-Figueroa (Ohio Univ.)
Instrument: Direct/Echelle

Problem(s) Encountered:
During the afternoon the mirror A/C monitor reported that the
mirror was below the minimum safe temperature and that the
heating coils were turned off. We found the correct menu item
and toggled the heater on. Later in the night there was a message
that the coils (we assume now the A/C coils) were frozen and that
the system was trying to heat them. Since there was no apparent
way for us to remedy the situation we did nothing. The condition
cleared by 3:40 AM. We're assuming that this was all normal
operation and that we acted correctly, but if not we'd like to
know about it.
