                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 HAFB called us to ask about a bright object that the control tower had
 seen around 21:55.  We could see something on the IR camera streaking E-W
 (or W-E) that left quite a trail.  My guess is it was a bolide or a
 fireball streaking across the sky.
 No problems otherwise with excellent seeing most all night
