MDM Observatory 1.3m Telescope Observing Report for 2021 Oct 18

Observer(s): Keighley Rockcliffe, Aylin Garcia Soto
Institution(s): Dartmouth College

Instrument: MODSPEC

Worked for 0.5 hours (first half of the night)
Bad weather most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   High Humidity all night.
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

We took several MIS flats. We paid close attention to the rising humidity. We opened the 1.3m dome briefly to see if skyflats were possible, but the humidity was rising quickly enough that we closed the dome. After that we took more MIS flats. The humidity remained high all night (>95%), so we did not open or take any more observations. The 2.4m dewar was accidentally left on and when it was discovered, there was no more liquid nitrogen left in the tank.
