                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
Turned cooling fans on at 19:00. Opened enclosure at 21:38 after the
threat of rain subsided.
We had a bat in the enclosure around 00:30.  I saw it zipping all over in
the enclosure with the IR camera, probably looking for a meal.
Clouds started coming back in around 01:00 and eventually swamped us at
03:40.
At shutdown I found we had a visiting guest on the intermediate level.
Our bat in the enclosure (or is that in the Belfree?) from earlier
in the night managed to make it down to the intermediate level.  It was
swooping all over the place but I couldn't manage to shoo him/her out the
door back to the enclosure level.  Eventually it hid somewhere on the
intermediate level.  Do bats feed on moths???  Hmmmm...  Anyway, I left
the light in the stairwell leading to the enclosure open and the door
open.  Hopefully it will attract insects to the light and draw the bat
to the insects and back up into the enclosure where it can escape the next
time we open.

 04:00  Rain sensor not working - Had light rain this morning  2001164
        and the rain sensor alarm did not go off. Covers on the
        telescope had been closed prior to this (I think).
