                ------------- ACTIVITY LOG --------------
 Observing Specialist: W.Ketzeback
 Another night where we did not open. The humidity was high and the
 cloud cover thick for the first half of the night. During the second
 half, the humidity dropped and the skies cleared around 03:30 however
 we were still seeing a fair amount of lightning off to our west and
 clouds were visible above the basin even though the radar was not
 picking them up. Under these conditions both the Sloanies and I
 decided it was rather risky to open. After an hour of clear skies the
 temperature dropped to meet the dewpoint and we were back to being
 under closure conditions. I spent the night entertaining myself with
 an introduction to TUI scripting.
