               ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 AZ Velocity Scale:
 Checkout - (temp 16.2) was 580, measured average 576.4, changed to 577
 Nasty clouds at sunset cleared around 21:30, but there were radar
 echoes not too far away, moving in non-standard directions.  So I
 waited a while to get better confidence in the direction they were
 moving.   At last I opened, we got some work done through varying
 cloud cover, and then the storms got too close for comfort and I
 closed.  Once the sky was clear and the storms more distant,
 humidity was too high.
