              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with borderline high winds and high dust counts.  We attepmted to open and aim east, then dust counts went critical and we were forced to close.  We did not open again until 20:46, being careful to aim east.  After 22:00 dust levels returned to normal, but high winds occasionally hit us.
NM01 was able to start on time.  Winds died down, and the night from 1 am was (aside from bad seeing) a good night.
