MDM Observatory 2.4m Telescope Observing Report for 2024 Apr 13

Observer(s): E. Moran et al.
Institution(s): Columbia

Instrument: CCDS

Worked for 8.75 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2 arcsec, Clear, Winds Moderate
   Mid: Seeing 2 arcsec, Clear, Winds Moderate
   End: Seeing 1.2 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

A very good night.  Everything worked well, and we had no problems
or delays.  Winds were pretty strong for the first 2/3 of the
night, and the seeing was mediocre.  The seeing improved
dramatically in the final 90 minutes, but there was noticeable
cirrus.  Oh, one problem -- in evening twilight, as we were
setting up on a flux standard, the guide probe wouldn't move.
Eric texted the solution, and things worked perfectly afterwards.
No impact on the science.
