              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan

Thin clouds in the afternoon grew thicker at sunset, and there was no chance of getting useful data.  Over the course of the night, threatening radar echoes also approached (but the rain sensor never went off), and the wind gusts spent a few hours over the limits as well.  Perhaps we will get some moisture as payment for a night of no data!
