              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with partly cloudy skies and a smattering of light drizzle which ended by 19:00.  Thunderstorms threatened us until 21:15, at which point they had dwindled enough that it was safe to open.  Skies were less than ideal, though, with enough cloud cover to play havoc with observations. Humidity spiked at 00:36 and we had to close.  Humidity dropped again, and we opened at 02:58.  Storms and the dew kept themselves at bay, and we observed until it was too light to observe further.
