              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Huehnerhoff
Good seeing until the clouds prevented observing.  Although the telescope
did not close I am counting one hour towards weather because science was
not possible.  Since the user could not observe through the cloud,
eAurigae data was taken.  Waves of dust/particle spikes closed down the
telescope twice during second half.
