               ------------- ACTIVITY LOG --------------
Observing Specialist: B.Ketzeback
Nearby radar returns again most of the night. We had nearby lightning
the end of first half. No precip. We opened at the start of Apollo
time under somewhat marginal conditions. While Russet was setting
up I was able to get an engineering measurement at TR2 for Nick.
The skies gradually improved after an hour and 4 reflectors were
measured during twilight.
