MDM Observatory 1.3m Telescope Observing Report for 2026 Jan 09

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

Instrument: Templeton direct

Worked for 7 hours (most of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity from start until 21:30.
   Beg: Clear, Winds Moderate
   Mid: Seeing 2 arcsec, Clear, Winds Moderate
   End: Seeing 2 arcsec, Clear, Winds High

Observing Summary:

At start mostly clear, cold, breezy, with scraps of fog blowing 
overhead and humidity too high to open. Around 9:30 the humidity
dropped quickly to well below the limit, so I opened and worked
on a single target until 4:40 or so when it was going to hit the
west limit.  By now the wind had picked up considerably, the 
seeing was poor, and I didn't have compelling targets remaining,
so I closed up and filled the dewar.
