MDM Observatory 2.4m Telescope Observing Report for 2021 Jun 15

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

Worked for 9  hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.8 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 2-ish arcsec, Clear, Winds Light & Variable
   End: Seeing 1.3 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

A surprise storm in the afternoon blew out completely by evening.
Eventually managed to get everything focused etc. -- 18 months 
away made me a little rusty! -- and got some good data.  The 
night was mostly clear though not photometric, with some high
cloud building in toward dawn.  The seeing ranged from OK to
fairly poor, but was never wretched.  I was delighted to be
observing again, and pleasantly surprised at how quickly it 
came back.

The telescope did bang, but I didn't keep an exact count. I'd
say at least a half-dozen times.
