              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Back to science!  Very unsettled weather first half as two storm outflows
clashed overhead.  We had only a few sprinkles but much uncertainty, so I
wasn't prepared to open until well into second half.  Seeing was poor but
not as bad as I expected.  Clouds interfered but didn't completely
prevent observations for the first hour, then the sky cleared nicely.
