                               ACTIVITY LOG
(* means a trouble report has been issued or appended to)
The telescope was opened at 21:50.  Brooke Skelton began with lamps at 19:55,
while we waited for some heavy clouds to dissipate.  We opened on time and
Brooke used DIS to obtain her data.  Gene Magnier was on hand to help Brooke
work with DIS.  Gene then began at 01:10, choosing DIS for the extent of the
evening.
I was the observer for the Lens Monitoring run.  I obtained data for 2237 and
2345.
The sky constantly was plagued with light to heavy clouds.
