                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: G.Saurage
Patchy fast moving clouds all about at sunset. Apollo reports signal on
two reflectors with really good signal on the last one.
Some DIS slitviewer issues at the beginning before twilight. When =93expose=
=94
was clicked it would just hang. Fritz Stauffer helped track down the
problem. The old 1.5 slit masks were the wrong size, as a result the
slitveiwer was not able to create an image. All was corrected before
twilight.
On and off clouds and mediocre seeing rest of 1st half.
2nd Half Observing Specialist: J.Dembicky
No problems
