Characteristics: Lights on object, Changed Colo

Blue/green blinking noiseless light stops in mid-air and gains altitude, turns white/red and flies away quickly.

Looked up to see flashing blue/green light moving overhead, the light flashed about once a second. After observing for a few seconds it stopped in mid air and flew straight up, turning white with a red light just below it. After flying up a distance it stopped and flew back the way it came at a fast speed, changing from white back into blinking blue/green. It disappeared momentarily and reappeared a few seconds later a little farther, about 6 miles away. It hovered high up still blinking for about 20-30 seconds and then vanished. No noise was heard.
