              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I was seeing some odd behaviour on both the alt and rotator during checkout.  Alt was giving me motion errors and rotator seemed to be delayed when I issued commands to it.  I reset both controllers.
Clouds started forming overhead around 00:30 and grew worse during 2nd half.  Local orographic clouds that were pretty fast moving but persistent.  By about 02:20 it was getting pretty difficult to observe anything with the clouds.
We gave up at 05:20 due to humidity and clouds.
