MDM Observatory 1.3m Telescope Observing Report for 2017 Nov 19

Observer(s): Halpern
Institution(s): Columbia

Instrument: Templeton 

Worked for 12.5 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 2.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.9 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.6 arcsec, Patchy Clouds, Winds Light & Variable

Observing Summary:

At the beginning of the night the telescope's RA coordinate
was off by 12 minutes of time.  I'm not sure why, since
there wasn't any problem like that at the end of last night.
I used the tilt meters and a bright star to zero the coordinates.
Otherwise there were no technical problem.  Well, there was
one network disconnect from the MDM side, at 4:45 am.  And
Owl failed to write an image at around 5:15 am.
Clouds for the last 3 hours of the night got worse,
covering my faint target.  Main dome slit didn't want to
close at the end.  Had to stop and start telescope to fix it.
