              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray & A.Townsend
Things started out clear with moderately good seeing. I thought things would stay that way for the class but, sadly, the clouds started rolling in. Wind hit 35 mph around midnight but then came back down, so it was just the clouds that was killing up. Then the humidity went up and we closed to be safe. We called it at 6:00am when it was clear we wouldn't be able to take cloud or sky flats. The wind started gusting high again at 6:30am and it looks like things should be pretty windy today! But the class had some good time and experience on sky with arctic.
No problems tonight.
