              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Thin clouds and excellent seeing - NICFPS narrowband had several images
better than 0.45" which I believe is a new site record.  For hours the
seeing (in IR) rarely got above 0.6".
The APOLLO laser was not working so we ceded time early.  This is not
counted as time lost to equipment since the problem was with the laser,
not with observatory equipment.
