              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy.  About an hour before sunset, the wind rose and kicked up quite a bit of dust.  Dust counts dropped to safe levels around 20:30, but the skies remained overcast with the threat of rain. Around 00:30 the humidity spiked over safe limits. The humidity stayed high for the rest of the night, and we gave up around 5:20.  No observing was done.
