                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 High winds and light rain before sunset delayed opening. Clouds thinned
 enough by 22:45 to open but did not stay that way long. Apparently the
 sucker-hole didnt last too long and we had difficulties with clouds for
 the remainder of the first half. The first half observer also complained
 several times about internet connectivity problems and an inability to
 autoget images. When pressed he admitted the problem was on his end with
 his wireless. Users are reminded that use of a public network (Internet2)
 can be highly unpredictable and they should observe from off campus at
 their own risk. Your results may differ.
 Second half went smoothly except for some minor problems with the
 slitviewer. The maskfile had inadvertantly been written out as a
 guide image confusing the observer why they could see no stars. It
 didnt take me long to correct this however in the process the
 slitview camera warmed a bit and objects were no longer visible
 in subsequent frames until it again cooled down. About 5 minutes
 was lost total for both problems.
