MDM Observatory 2.4m Telescope Observing Report for 2013 Apr 19

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

Instrument: OSMOS

Worked for 10 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2.0 arcsec, Clear, Winds Calm
   Mid: Seeing 1.2 arcsec, Clear, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Overall, we had no problems with the telescope, the weather, or the data. We observed 
four targets from our list, three of them for 1.5 hours, and one for just one hour, 
before morning twilight. We were able to get a great set of twilight flats in the evening,
great calibration data, and while the seeing at the star of the night was not very good,
it settled down when it really mattered. We only ran OSMOS in long-slit mode tonight. 

One of our objects has a really interesting kinematic signature at 15 kpc from the
source, potentially as a result of the merger it is undergoing. Another object had
a 4kpc radius NLR with a very narrow emission signature. Pretty neat stuff. 

Pointing was always great, and the tracking went well. The telescope was way out
of focus when we started, but that was easy enough to fix. Thanks!
