              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Stopped getting data at 00:30 when we could no longer push through the
thick clouds. Closed at 00:58. We did not open the rest of the night due
to clouds and the incoming front. Gave up at 05:00. Tspec aux tank showed
81-82 K temp range tonight. Images looked fine.
