              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
Although the telescope was open almost all night, most of the time we
were unable to get data through the clouds.  The second half observer got
a couple of hours of data but estimated that they would not be usable; I
did count that time towards observing since it was at least good enough
to try.
I did a little bit of pickup science on Epsilon Aurigae and also a
positional confirmation that was requested.
