              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Clear night with poor seeing.
Some trouble with DIS guiding.  While using boresight guiding and
Horizon+90 the star jumped +x 50 pixels (along slit).  This occurred 20
minutes before crossing meridian.
During morning checkout the mirror covers would not respond to commands.
Similar to the problem Russet was having.  The eyelids would open and
close but not the covers.  I closed the covers manually.  Resetting the
keyswitch and moving back to auto did not help.
