MDM Observatory 1.3m Telescope Observing Report for 2019 Oct 30

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

Instrument: Modspec + echelle ccd

Worked for 12 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1+ arcsec, Clear, Winds Light & Variable
   Mid: Seeing 2-ish arcsec, Clear, Winds Light & Variable
   End: Seeing 1+ arcsec, Clear, Winds Light & Variable

Observing Summary:

Another nice clear night, with seeing a bit more variable than 
before.  Just a tiny bit of cirrus early on, probably some
during the night as well but nothing noticeable.

No problems with the equipment, but once again, the 
echelle pattern noise is really quite problematic for 
spectroscopy of faint objects.
