              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
At the start of the night it looked like we had some threatening weather, with lots of radar
returns, moving down from the N on us.  The system actually moved to the SW and just missed us.
Even though we had some passing clouds we were able to observe without any problems.
Elevated dust levels tonight.
