I was on perimeter guard duty with 3 others who were off watch and asleep.
I remember this vividly and can't ever forget it.
While looking to the North West, right above the treeline, I noticed a bright luminous object.
It was silverist/blue/white. I noticed it move toward the South a little then stop on a dime, leaving a trailing tracing effect, a blur of light, from start to stop. Repeating this numerous times.
When it was almost due South it shot upward at about 45 ° back toward the North.
I can't describe the shape, size or distance accurately. It was distant several miles, best guest.
It deffinately wasn't any of our aircraft.
