              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy.  There was some storms to the south of us, but they stayed at bay. The storms faded and the skies got somewhat clear, at least for a while. Around 23:00 clouds began to thicken hampering observations. Clouds continued to thicken, and we closed at 03:10 with the rain alarm going off shortly afterwards.  The rains cleared and we opened again at 04:20. We stayed open until dawn.
