                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 The night went by smoothly. There was some confusion the later part of
 first half when the observer was uncertain which filter nicfps was in.
 I verified that the mask position was correct however was uncertain of
 the position of the H filter, even after I recentered the wheel, until
 I forced the filter wheel to move to the absolute position.
