| Name | James H |
| Experience Level | 3/5 |
| Remarks | I was driving eastbound on I-276, just past the King Of Prussia Mall in Pennsylvania, Wednesday, October 18, 15:00 local time, when I saw the fireball suddenly streak into view, right before my eyes; it looked exactly like a shooting star but in full daylight; there were no clouds in the sky at all. It grew in intensity from a thin streak to quite a long, very very bright white streak. It modulated to a pale green and then back to very bright white and then disappeared. the entire event lasted no longer than 2 - 3 seconds at most. There was a good deal of traffic on the road at the time (rush hour was just beginning at 15:00 local time) so hopefully others saw it and will file reports. Probably fell into the Atlantic Ocean off the Jersey or Maryland shore. Excellent sighting! |
