Was driving at time of observation. Slowed down and opened window but did not hear any sounds. No oncoming traffic to interfere with view. Lost sight when view blocked by trees. Appeared white like a car headlight. The red streamer was a deeper red like a car\'s brakelight. The green streamer was a very bright green like new growth on a tree in the springtime. Both streamers came from \"top\" of fireball. Total observation time was approx. 15 -17 seconds. (I missed this on previous screen - I was traveling NW on Horsham Rd.)
