              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, but with storms to the west of us. We risked an opening at sunset. It was partly cloudy, with poor seeing. Around 23:45 the storms to the west got too close for comfort. It was frustrating, becuase we were in a suckhole, clear skies overhead, but there was rain right in Alamo. The rain began to burn out and we opened at 02:10, trying to catch a suckerhole between the two waves of rain sweeping by us. The second wave of rain dried up before it got to use, and we stayed open for the rest of the night.
