MDM Observatory 2.4m Telescope Observing Report for 2014 Jan 28

Observer(s): Hainline, French
Institution(s): Dartmouth College

Instrument: OSMOS

Worked for 13 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 1.0 arcsec, Clear, Winds Calm
   Mid: Seeing 1.3 arcsec, Clear, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Tonight we had some great conditions, which we capitalized on to both
re-familiarize ourselves with the instrument, but also to get some
excellent spatially resolved data of four objects in our sample. The
seeing was a little over an arcsecond, and while clouds were looming
at the beginning of the night, they dissipated quickly, and we had 
clear skies and calm winds. 

The biggest issue lies in the fact that the images seem to be rotated
by 90 degrees when they read out from OSMOS. Typically, the wavelength
direction is left to right, while the spatial direction is up and down.
Indeed, this is built into osctrtask, the python script written for
centering the slit with OSMOS. Tonight, however, we were seeing that the
wavelength direction was up and down, and the spatial direction right
to left. This is a minor inconvenience, but if there's something simple
that can be done to fix this, that would be great.

Also, about 1/3rd through the night, the prospero status window listed Filter 2
as being  * **** , and wouldn't accept any movements. Lucky for us, we had
Filter 2 set as open, and didn't need to use it, but I just thought I'd mention 
that it wasn't responding to prospero commands.
