                  ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: J. Barentine
 Opened at 18:35 under clear skies and light winds.  Seeing was passable
for most of the evening but around 22:00 it became clear that the stellar
profiles were getting to be increasingly elliptical.  Seeing problems were
replaced by clouds after 22:00 leading to closure around 23:30 when it
became clear the sky wasn't going to.
 2nd Half Observing Specialist: J. Dembicky
Clouds the second half pretty much kept us closed until around 3AM.  I did
a quick focus (thru clouds which made it interesting) and then turned the
instrument over to the 2nd half observer to try their luck.  Unfortunately
luck was not with the 2nd half observers and clouds quickly dashed the
hopes of collecting anything useful for the night.  We gave up around
04:30 when the clouds got really thick.
