                ------------- ACTIVITY LOG --------------
 Observing Specialists: B.Ketzeback, J.Davenport
 AZ Velocity Scale:
 Checkout - (temp 21.4) was 580 measured average 579.99, no change
 Apollo got returns on just one reflector before heavy cloud cover forced
 us to close.
 By midnight the skies had cleared enough for us to open. Seeing was
 rather poor at greater than 2 arcseconds. Around 12:45 the clouds
 again moved in which greatly improved the seeing. The skies remainded
 partly cloudy for the rest of the night.
