MDM Observatory 2.4m Telescope Observing Report for 2015 Sep 24

Observer(s): Baldassare, Foord, Hodges-Kluck
Institution(s): Michigan

Instrument: OSMOS-B/1.2  slit

Worked for 11 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 1.3 arcsec, Clear, Winds Calm
   Mid: Seeing 1.3 arcsec, Clear, Winds Calm
   End: Seeing 1.3 arcsec, Clear, Winds Calm

Observing Summary:

The telescope lost pointing a few times crossing the zenith and
we needed to manually restore it via the tilt method. I am not
sure what caused this, as after we set the offsets the third time
it was fine the rest of the night, crossing the zenith or no.
Otherwise, everything worked fine and we obtained spectra for 
five quasars and some standard stars. The twilight flats did not
turn out well, so we will need to wait until tomorrow to do a
quick-look reduction.
