MDM Trouble Report for 2015 May 12

Telescope: 1.3m
Observer(s): Meghin Spencer (University of Michigan)
Instrument: 4K

Problem(s) Encountered:
We filled the dewar at the beginning of the night, 
but around 1am we noticed that the temperature reading was around -80. 
We refilled the dewar at that time but noted that it didn't take very long to refill. 
However, when we checked the temp half an hour later it had cooled down to about -95.
Now at the end of the night it is back down to -107.
We also noticed that using the call roi4k or call roi2k commands in Prospero issued a pile of errors.
