                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
   I arrived under partly cloudy skies that continued to get worse. I
opened the dome at 16:50 MST to allow for cooling and sky flats. This was
mostly practice time for our UM trainee. The clouds continued to approach
and we closed at 18:52 MST. Afterwards, I was inspecting DIS and found
the fill tube flange was leaking, likely explaining where our missing lN2
has gone over the last few days. PR submitted.
   I continued to work on plotting for the annual report and HTML Manual
documents. Some of the instrument fill sections and Echelle docs have
been updated.
 Observing Specialist, 2nd Shift: Russet McMillan
 It remained cloudy and windy during second half, except for a sucker
 hole lasting all of ten minutes around 02:30.  We opened for a short
 while but were never even able to focus before closing due to more
 clouds and high winds, so I left the time under the Weather column.
