              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Zeroed the NA2 rotator during checkout.  It was off by 0.063.
Delayed opening due to thick cloud cover and high humidity.  Humidity high
(below closure limit) but stable at time of opening.
First half was poor seeing but second half improved to sub arcsecond seeing.
All instrument performed well.
