              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
Night was lost to clouds, rain, lightning, high humidity, high winds, and nearby radar returns.  During second half we had power outages.  Each lasted a few seconds, and came in groups of about 2 or 3.  Utility power always came back.  This started at the same time that lightning got within about 12km of us, and continued even after the lightning was gone.  I reset the enclosure when I left, although I think it likely that the power will flicker again. Gave up for the night at 05:09
Mounted GFP for daytime testing.
