              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
At 2040MT the echelle saddle bag was turned off as part of warming/pumping
of the camera.
Wind was a big problem during the first half.  At 2055MT a direction
restriction was imposed on observations.  The telescope was able to track
well with its back to the wind.
Closed for dust spike at 0130MT, dust subsided at 0300MT but thick clouds
moved in.  Opened late in second half.  Clouds forming to the west of site
subsided enough science.  Seeing was highly variable and terrible after
opening.
After closing vacuum pump was turned on and pumping down vacuum line to
ECHELLE.  Camera valve was NOT opened.
