              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
The streak broke.  It was not perfectly clear at the start of the night, but we were able to open on time anyway. Slight haze gave way to very transparent and still skies by 22:00.  Occasional thin clouds, but stayed nice.
0100 had some high haze roll through. Occasional thin clouds continued throught the night, but nothing terrible, and we stayed open until dawn.
