              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Partly cloudy first half, clearing second half.  We closed for a while due to nearby radar returns, and frustratingly there was still precipitation quite close to us for a while after the sky cleared, but finally we were able to reopen.  Everything worked well.
