MDM Observatory 2.4m Telescope Observing Report for 2017 Jan 17

Observer(s): John Thorstensen
Institution(s): Dartmouth

Instrument: modspec + echelle CCD

Worked for 3 hours (part of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity all night.
   Beg: Clear, Winds Calm, humidity too high
   Mid: Seeing 1 arcsec, Clear, Winds Calm, open
   End: Clear, Winds Calm, humidity too high

Observing Summary:

Another frustrating night -- beautifully clear almost from the 
start, but too humid except for a usable 3-hour chunk in the 
middle.  Kitt Peak re-opened in the hour before dawn, but it's
still really humid on the southwest ridge as I write this (6:10
AM MST).  Winds were notably light, sometimes zero.

Tonight's observations took the dome only to the west, and when
I homed it, it overshot the contacts by about 18 inches again - 
dome was to the right of the contacts as viewed from inside.
