              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Huehnerhoff, A.Shelden
Closed when sudden clouds and radar appeared at 2030MT.  Decent, stable
seeing  during the night.
Mirror covers worked great.
Azimuth oscillations occurred at 0800UT (az=-17, alt=38).  Started after
axis init.  After cycling stop button oscillations returned.  Slewing to
different position correct problem.
