                ------------- ACTIVITY LOG --------------
 1st Half Observing Specialist: R.McMillan
 The night started out partly cloudy with variable seeing, but after
 21:30 radar returns showed weather heading our way.  I closed just
 before the first sprinkles, which eventually led to a thunderstorm.
 The GFP was working properly tonight.
 2nd Half Observing Specialist: B.Ketzeback
 Rained off and on for the first few hours of second half. We were
 able to open at 04:00 when the clouds quickly broke up. Everything
 went smoothly for the rest of the night.
