                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J. Dembicky, R. McMillan (2nd half)
The night started out partly cloudy but the humidity was on the rise and
a large storm cell was just off to our East and another to the West.
Lightning was also present in within 8 miles. I diverted opening until
conditions improved.
I opened the enclosure at 23:15 under partly cloudy skies but what
appeared to be improving conditions.  I also called Jon D. to come in to
do the collimation (and Russet since she wanted to be here as well).
Russet came in around 23:50 just as we were getting ready to start the
primary mirror collimation. Finished the primary collimation around 00:25
just as clouds started to move in again.
We re-opened again at 01:25 to try to get some tip-tilt measurements for
the NA1 and TR4 ports with hopes of maybe a pointing model afterwards.
We finished a rough tip-tilt measurement for the Echelle but it may need
some refining yet.
We finished a 72 point pointing model on the NA2 port.  Then checked the
tip-tilts on the Echelle to determine if more refining is necessary,
they looked good.
We proceeded to do a tip-tilt for the TR4 port and then proceeded to take
some SHACK data.
