MDM Observatory 1.3m Telescope Observer's Report for 2003 Mar 25

Observer(s): Martin Bureau, Kambiz Fathi
Institution(s): Columbia, Nottingham

Instrument: Echelle f/7.5 Direct Imaging

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

Seeing and Weather:
   Beg: Seeing 1.8 arcsec, Cirrus, Winds Light & Variable, PSF gradient
   Mid: Seeing 2.2 arcsec, Cirrus, Winds Light & Variable, PSF gradient
   End: Seeing 1.8 arcsec, Cirrus, Winds Light & Variable, PSF gradient

Observing Summary:

Spent first 2-3 hours figuring out the CCD orientation, calibrating the pointing, focusing, and generally getting acquainted with the telescope. Things proceeded smoothly afterwards. Acquired medium-deep exposures of 6 objects.

A 30% PSF gradient across the field-of-view may significantly complicate the data reduction and analysis.
