              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden
First half was almost completely lost to high winds and high dust.  They returned by about 04:00, and I pushed the limits, only because it was close to 12 degree twilight.  Closed at 04:50.
No other problems to report.
