                ------------- ACTIVITY LOG --------------
 Observing Specialists: B.Ketzeback, J.Davenport
 Due to a test at White Sands Missle Range, APOLLO was unable to
 range tonight. They turned their time over to the NAIC group which
 made good time of the twilight and first hour of the night. Pointing
 was greatly improved after I zero'ed the rotator before tonights run.
 Around 10:15 clouds started appearing in the area. Within 5 minutes
 wind speeds increased to greater than 40 mph, dust levels spiked
 and humidity climbed. We closed quickly. Skies cleared again after
 1am however dust and wind remained a problem for the remainder of
 the night. We never reopened.
