               -------------- Activity Log --------------
Observing Specialist: N.C.Hastings
   The telescope was closed due to threatening weather and clouds.
Thunderstorms surrounded us and refused to let up! During the cloudy
time the UW program took cals, flats and bias frames. Later on I
switched out the aperture in the echelle to the 1.6" x 1.6" square
aperture. This is a process that is a little involved due to the light
tight taping we applied a while back, so any aperture switches should
be minimized and if absolutely necessary, given at least 24-48 hours
notice on the request. It was requested early for this switch so there
was no problem.
   The dewar on DIS had been on for over 5 days and still showed
nitrogen on the gauge, but felt very light, so I switched it out. It
has the standard Full/Empty designation. I also switched out the NA2
fill dewar and the echelle fill dewar recently, so there are no full
dewars left on the standby rack.

used is north=0 degrees, east=90 degrees. The dust count is for the
particles > 1 micron per 0.1 cu.ft.
