                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
    The first wave of clouds from the approaching weather system kept us
closed until 19:50, but we then opened for a hole and started gathering
data. There were no problems tonight other than weather.
	The Princeton group ran the DIS slit viewer without incident as has
become the norm. I am recommending that we start the remote operation of
the slit camera officially very soon.
	Clouds returned with higher winds around 22:00.
 Observing Specialist, 2nd Shift: Jack Dembicky
Clouds were starting to thicken when I arrived and the wind was growing
stronger as well.  Clouds became too thick to observe thru at 23:25 and
I closed the enclosure due to clouds and increasing wind speed (33MPH
gusts) at 23:45.  We hit the humidity closure limit at 02:45 (although we
were closed long before this point due to clouds).
Seeing was horrible at 3-4 arc sec due to the approaching storm.
