              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
Night was very windy and cloudy throughout.  Patchy clouds at best, and the wind was mostly in the red.  The tracking stayed smooth all night, and the radar looked somewhat ok, so I pushed the closing limits and we stayed open all night.  I pushed it until about an hour before twilight started, then closed.
Yuri Izotov was observing from Germany, and we had periods of slow connectivity and waiting for information to get through.  But we limped along and had a productive run.
