              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
UW08 and UW07 swapped nights tonight.  UW08 will take UW07 time on Saturday night.
My observer gave up a bit early.  I called Candace (NM03) and gave her the remaining time since she could observe Venus on short notice.
The sky was nice and clear all night but seeing was rather poor.
No problems tonight.
