               ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clouds and rain and lightning and high humidity kept us closed for
 most of the night; some sprinkles came with no advance warning on
 radar and made me very paranoid, but eventually we were able to open
 for an hour plus some twilight time.  Pointing seemed adequate (with
 DIS, which has a large enough field of view to be forgiving), but
 magnesensor errors were still large.
 DIS will be left mounted during the day for the use of the class
 on-site.
