              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The first test slew gave me motion errors on both alt and az.  I did an axis stop/init and stop button cycle.  The next slews, individual axis this time, were both fine.  No problems afterwards for the test slews.
No problems tonight.
