MDM Observatory 1.3m Telescope Observing Report for 2021 Jun 14

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

Instrument: Andor + BuckeyeFW

Worked for 4 hours (off and on through the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from start until midn..
   Beg: Overcast, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 1.5 arcsec, Clear, Winds Light & Variable

Observing Summary:

It clouded up pretty rapidly in late afternoon as clouds drifted
over mostly from the east, which is a bit unusual.  I was open
briefly to get a flatfield in twilight, but it was impossible
to acquire a target so I closed for a couple of hours.  

Around midnight it started clearing; 
there were intermittend clouds afterwards but by a bit after 1
it was pretty clear.  I managed to get good timeseries on two
targets.  Seeing was plenty good enough for my purposes.

Other than the clouds, everything worked very well, and
it is great to be back on the mountain.
