MDM Observatory 1.3m Telescope Observing Report for 2010 Mar 13

Observer(s): Corrales & Schroeder
Institution(s): Columbia

Instrument: 4K

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:
   Beg: Seeing 1.2 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 1.2 arcsec, Cirrus, Winds Moderate
   End: Seeing 1.0 arcsec, Clear, Winds Light & Variable

Observing Summary:

We discovered that the 4K configuration is somehow damaged.

This can be seen on /lhome/data/test.0001.fits.

The other formats are fine.

The readout in general seems to bleed charge across the CCD for saturated pixels regardless of format.

This produces ghost images on each of the four regions of the chip.

The dec drive seems to continue to oscillate at H.A. = -3:00.
