              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out perfectly clear! The snow was blinding, the wind was biting, the cold was freezing.  Did I mention the wind?  Bill gave us a direct order to keep the barn doors shut while the wind was above 20mph.  We despaired.  Winds were kicking up to over 35mph.  Would be open at all?
Then, around 2:30, as the wind was continuing to drop, we hit the limit! Slamming back our coffee and rubbing our eyes, we opened the doors and took to the skies! The dying wind provided us with subarcsecond seeing (yeah!) and WY01 was able to get some good data.
No problems tonight
