                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
Some cirrus at the beginning of the night which made focusing rather
difficult. Then the skies cleared and seeing was around an arcsecond
for much of the first half. There was one crash of the dcamera but
recovery took just 2 minutes so no loss of time was counted.
Second half was mostly smooth however I did see some minor examples
of the boresight moving by itself as described previously by Jack in
PR#529 where ctrl-click would not center on the boresight and the
red and blue crosses in the images would grow farther and farther apart.
The problem finally reached a point where the star was drifting an
unacceptqable rate away from the slit for the observer.
After several failed tries to get back to a normal mode I noted that
the ecam image was ever so slightly subframed along the left edge
of the field. (see proc-e1850.fits to proc-e1856.fits). The problem
corrected itself once images were returned to full frame mode.
