              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 A lovely clear night that started with half-arcsecond seeing; it
 degraded to over an arcsecond in the IR and nearly 2 arcsec at 530
 nm, during the middle of the night (or perhaps just when pointing
 close to the wind direction), then improved to subarcsecond again
 during second half.
 We had no drive harmonics problems, but we were only in the
 northwestern part of the sky for a short while.
