MDM Observatory 2.4m Telescope Observing Report for 2025 Jul 01

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

Instrument: OSMOS

Worked for 0.7 hours (part of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Overcast, Winds Light & Variable
   Mid: Seeing 1.3 arcsec, Patchy Clouds, Winds Light & Variable
   End: Patchy Clouds, Winds Light & Variable

Observing Summary:

Quite cloudy and a bit unstable early, but it dissipated to 
nothing but patchy high cloud which remained all night.  KPNO was
closed due to dust, which again didn't seem that bad to me, so
opened briefly in an especially clear interval just after 
midnight.  This persisted long enough to get a few nice spectra,
but then guide star disappeared and the party was over.  The 
sky was touch-and-go for the rest of the night, but never good
enough to try to work; Kitt Peak's closure put a thumb on the 
scales to keep me closed.
