              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out clear with good seeing. Dust got high at sunset but not enough
to close. However, after midnight, the clouds started rolling in. NA02 finished
their second night and did great! However, the clouds stopped their progress at 6:30
and we called it quits.
No problems tonight.
