MDM Trouble Report for 2016 Dec 08

Telescope: 2.4m
Observer(s): Douglas, Núñez, Gibson (Columbia University)
Instrument: Modspec/Nellie

Problem(s) Encountered:
Near the end of the first half of the night, the dome lost track of its position.
We discovered this when we noticed that the dome was partially obstructing the telescope in one of our exposures.
We manually fixed its position and it kept working OK after that.
But at the end of the night when we brought the dome home, it was pointing to 20 degrees instead of 320, so we moved it home manually.
