                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Jack Dembicky
 Clouds prevented opening during first half until around Midnight.
Although I did manage to focus (which was difficult with clouds dimming
my focus star), by the time I had finished the clouds were too thick
again to get any useful science.  I closed the enclosure again at 01:00
when I went up to change instruments.
We never opened again for the remainder of the night due to clouds and
then clouds and a dust event at 03:00 that lasted the remainder of the
night.
