              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS temps @ 00:40 198, 185
Dust/smoke kept us closed until 00:30.  My first half observers could not use that
short of time so they ceded the remaining time to the second half.  Dust was still
elevated during 2nd half but mostly stayed below 4000 cts.
DIS temps @06:00 188, 184
No telescope problems tonight.
