               ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Davenport
Opened right at startup and was shutdown by clouds.  Clouds cleared and
humidity came down enough to open around 03:30.
Pointing was a bit off 1st half, but decided to work through it. 2nd half
pointing seemed worse. Ran na2point but didn't see much improvement after
set inst=dis. Had to run 3 times until we got better pointing. Seems that
we have had lots of pointing troubles in the past month...
By the time I got us pointed and focused the humidity came back up and we
closed again... an ill fated night.
