              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Lots of fog and high humidity.  Once the humidity dropped, I found lots of ice on the catwalk.  As there was only an hour left until twilight, we decided not to risk it.
See engineering email for details.
Zeroed NA2 rotator
Reset axes controllers
Checked and adjusted DIS focus
Ran TCC 1.0.7
Caused a TCC command collision (by accident)
Tested Jack's rotator slew problem
Tested the axis init infinite loop problem (no problems)
Updated Shack-Hartmann computer
New mask files
