MDM Observatory 2.4m Telescope Observing Report for 2022 Apr 20

Observer(s): Alejandro Nunez, Luna Wang
Institution(s): Columbia University

Instrument: OSMOS/B

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

Seeing and Weather:
   Beg: Clear, Winds Light & Variable
   Mid: Clear, Winds Light & Variable
   End: Clear, Winds Light & Variable

Observing Summary:

Clear skies, low humidity, and light to moderate winds prevailed during the whole night.
Seeing was good too.
Early in the night, we accidentally attempted to move the 1.2  slit out while the finder
was still moving out. There was a crack sound when it happened. In our quick spectral
reductions, the peak of the aperture has a wonky shape, which we suspect is due to a 
faulty slit.
