                               ACTIVITY LOG
The telescope was opened at 19:10.  Bernadette Rodgers was the first observer.
We observed the HAEBE monitoring program.  No problems.
Patricia Knezek was the second observer.  She observed 2 faint galaxies.
Comments:Things went well, except for the occasional cloud.  It got
progressively
better as the night wore on.  The only things were: (1) it looks like
there might be a charge transfer problem with the red chip.  I have some
bleeding charge traps in my red images. This also seemed to get better as
the night wore on.  At the beginning of the night the bleeding looked
quite bad.  The blue chip behaved beautifully. Also (2), the guider died
and Tia was unable to get it going again, so we had to guide by eye at
the end of the night.   Other than that, things are fine!
Note: The guider was working fine all night.  The reason I had a bit of trouble
near the end of the evening was due to the area of the sky where the target
was had a sparse number of stars to guide with and most were extremely dim.
Patricia's object was 19th Magnitude.
