MDM Observatory 1.3m Telescope Observer's Report for 2003 Apr 05

Observer(s): Martin Bureau, Davor Krajnovic
Institution(s): Columbia, Leiden

Instrument: Echelle f/7.5 direct imaging

Worked for 11 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.6 arcsec, Cirrus, Winds Calm
   Mid: Seeing 2.5 arcsec, Clear, Winds Calm
   End: Seeing 2.5 arcsec, Clear, Winds Calm

Observing Summary:

The sky was devoid of clouds but with bad transparency all night. The seeing started good but quickly dereriorated and stayed around and above 2 arcseconds for much of the night. Accordingly, we obtained deep/long exposures of our sample objects without attempting photometry, completing 7 galaxies.

No probblem at all occured except that the pointing was quite wrong at the begining of the night (about 1 degree?). We recalibrated it by manually searching for a Mv=2 star with the guider positioned at the center of the CCD and refining the pointing on a subsequent object (lost about 30min in the process).
