MDM Observatory 2.4m Telescope Observing Report for 2014 Feb 04

Observer(s): Seth Cohen
Institution(s): Dartmouth College

Instrument: OSMOS

Worked for 3 hours (first half of the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds from 12:00 until end.
   Beg: Seeing 0.9 arcsec, Clear, Winds Calm
   Mid: Overcast, Winds Calm
   End: Overcast, Winds Calm

Observing Summary:

First, the weather: clear with sub-arcsecond seeing until around
midnight, and then overcast the rest of the night.

However, I couldn't begin observing until a few hours after sunset
because of Prospero.  When I tried taking twilight flats, Prospero crashed.
I could not restart it in time to take flats.

But then it got worse.  When I tried to take a focus frame,
the monitor displayed the correct image, but Prospero did not save
it.  Instead, Prospero added twiflat.6046, a twilight flat I had taken 
the previous night, to the main directory.  When I tried to take another
focus frame, Prospero added twiflat.6047.  No amount of fiddling or 
restarting Prospero changed this; all Prospero wanted to do was show
me last night's twilight flats.

I eventually called Eric, and he worked for a while from home (thank you!)
and finally got everything working again.  It's a good thing, too, because
the clear part of the night had sub-arcsecond seeing.
