MDM Observatory 2.4m Telescope Observing Report for 2024 Dec 05

Observer(s): John Thorstensen, Ricky Mendez
Institution(s): Dartmouth

Instrument: OSMOS

Worked for 8 hours (part of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Calm
   Mid: Patchy Clouds, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Mostly clear, with a raft of clouds coming over around 9:30 
which shut us down.  I took this opportunity to nap for a while
since I'm about to drive Ricky Mendez to the airport.  

Experienced a few guider jumps -- these seem to occur largely 
in the northwest (though statistics are limited) and always
are corrected by mashing the WEST button on the handpaddle, so 
it's as if the drive cuts out briefly.  Autofocus continues to
mostly work but with some odd jumps - at start, we were about
100 units too high.  I didn't chase it during the night -- some
images during the night had 5+ pixel FWHM, but with smooth, 
symmetrical profiles indicating slightly soft seeing rather than
focus.
