------------- ACTIVITY LOG --------------
Observing Specialist: J. Dembicky, J.Huehnerhoff
Night started out cloudy and dissipated to foggy then clear with high
humidity the remainder of the night.
The azimuth controller had a servo error at UT 00:56. Contacted Fritz and
was resolved.
There was a hissing noise coming from the ECHELLE shield LN2 tank.  It
appears as if the fill actuator is not closing completely.  A problem
report has been filed (1055).
