              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
High wind and dust at start of night. Counts got up past 70k for 1micron particle size at one point. But it started to die down and got to a manageable point around 11pm.
Weather prevented JH04 from being able to use their time. We gave up on using Nicfps around 11pm.
Dust counts were higher in dome than outside around midnight. (7k inside dome and 3k outside) May be worth checking and making sure the press fans are working properly.
Once dust and wind cleared, clouds and radar moved in.
Gave up just before 6:30am. Radar and clouds never cleared enough in time for productive science to take place.
