------------- ACTIVITY LOG --------------
Observing Specialist: G. Saurage, J.Huehnerhoff
Variable weather with a cloud system moving in early in the evening
turning to thick fog in the morning.
During checkout a pointing model was started.  After terminating the
pointing model to let the observer take cals the altitude controller
errored.  This occurred at UT 00:10:46.  The controller reset itself and
upon reboot loaded the wrong position which was approximately 20 degrees
off. A set.position and more test slews crossing magna-sensors corrected
the problem.
After the observer took cals long tracks at high altitude were performed
with debug on.  The first track was from UT 01:48 to 03:20 at high
altitudes in the North.
The second long track was at moderate altitude (60 degrees) in the South.
Tracking seemed stable till meridian crossing when there was a servo
error.  This occurred at UT 04:15:00 at 60.7 degrees.
At UT 06:11 there where inconstant readings with the dewpoint sensor.  The
dewpoint temperature was reading -14 which it corrected upon next update.
This occurred when the difference was 0.1.
