              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with high winds and a LOT of dust. We were getting up to 40K on the 1um particle counter. Everything was clouds, clouds, clouds except for maybe 20 min when I could see the stars. There were radar returns and low clouds for most of the night. Things were not going to improve by the JH05 users minimum time ended and I called it.
No problems tonight.
