              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The wind dropped sooner than expected, and the dust dropped mid-evening.  But the clouds remained thick for a long time, and when they thinned the wind came back up.  And when the wind went down and the sky cleared, it was already twilight.
