              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with lots of clouds that never left. We had high winds towards the middle of the night, peaking at 50 mph. There was a light spot of rain that lasted a few seconds but that was it. There was no real hope of opening tonight and when we reached the usable limit for NM02 I called it.
No problems tonight.
