                               ACTIVITY LOG
The telescope was open tonight at 18:20.
Alan Dierks was the observer for the DD01 (DSMD).  He stated that everything
went smoothly.
Connie Rockosi was observing the second half using SPICAM.
Comments: Last night's trouble driftscanning was traced to a software
versioning problem.  Thanks to Gene Magnier for tracing it down for me
earlier this afternoon.  Clouds prevented any photometry, but I got what I
hope will be a useful set of cloud flats in 3 filters.
