                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd Shift: Jack Dembicky
A problem was encountered during checkout with the tertiary.  PR was
submitted and Craig also spent several hours diagnosing things.  The
tertiary was left in an unknown position and will be worked on tommorow.
It could have been moved to a known position but Craig and Jon wanted it
left if there wasn't any chance of opening tonight (there wasn't).
We could not open due to lightning, clouds, high humidity and snow.
We also had a close lightning strike around 19:15 tonight.
The snow program was started around 20:45 with lt. snow falling all night
long and becoming heavier towards the morning.
Russet did not come in tonight for 2nd half due to unsafe road conditions.
I did the LN2 fills for her at the end of the night.
