noticed what i thought at first was a new really well lit cell tower. then the landing lights of a newer aircraft, but when 10mins. whent by, i marked the spot where i was standing, and the elavation, by physical referance, also marked its position by landmark referance. it remained what appeared completly motionless for an additional 11 mins. and then moved what had to be at least 1500 feet so fast that you couldnt precieve the motion’straight up. then moved south maybe 250 miles south in the same manner. then vanished.
