              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Storms passing through from the southwest all night long. We got a little bit of rain and a lot of clouds. We didn't open.
Restarted strip chart mac; CPUs were at 100% and computer was lagging badly, az_alt_v and az_alt_current plots had crashed entirely.
For engineering I worked on documentation updates.
