              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds prevented us opening until 22:45
More telescope engineering tonight.  Excellent seeing when we were able to be open!
Engineering log sent in separate email.
Clouds closed us down just as I got the SPIcam instrument block completed.  A few sprinkles around
01:00 but nothing much, just thick clouds the remainder of the night.
I called it at 04:00 with heavy overcast skies.
