MDM Observatory 2.4m Telescope Observing Report for 2009 Jan 09

Observer(s): Julie Skinner
Institution(s): Dartmouth College

Instrument: Echelle

Worked for 12 hours (all night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   High Humidity from 0130 until 0230.
   Beg: Seeing >2 arcsec, Clear, Winds Moderate, hazy
   Mid: Seeing >2 arcsec, Clear, Winds High, hazy
   End: Seeing >2 arcsec, Clear, Winds High, hazy

Observing Summary:

A poor night indeed: bad seeing, high winds, high humidity, & a hazy sky.

The telescope was off in its pointing at the beginning of the night, but I fixed that fairly quickly.

The only real problem I had was that the hose for the LN2 dewar broke mid-fill in the evening.  
I just reattached the  broken  end to the metal pipe and that seems to be working ok, although there was some leakage from the hose when I filled this morning.
