MDM Observatory 2.4m Telescope Observing Report for 2017 Jun 19

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

Instrument: Modspec + echelle

Worked for 8 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Moderate, deep red sunset
   Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 1.2 arcsec, Patchy Clouds, Winds Light & Variable

Observing Summary:

A pretty nice night; mostly clear, though with some high smoke 
around and occasional broken cloud.  Seeing was generally pretty 
decent, despite it being very hot - the night started out around
85 F and ended up around 80.

The telescope is not pointing well at high dec, and could use
a pointing model tuneup, though that's best performed after the 
refit.  The dome worked well.
