Reports Report 223d (Event 223-2013)
| Observer | |
|---|---|
| Name | Chuck P |
| Experience Level | 3/5 |
| Remarks | phenomenon was bright; overcame significant downtown city light pollution; event first drew attention to itself due to rapidly moving shadows of utility poles on lit city street and then by reflected highlights on light poles; did not get video/photo of fireball, but immediately recorded a series of photos, videos, GPS maps and a mosaic'd 360 panorama to record exact location of feet of observer (me) and path of fireball relative to city structures. I'm guessing the event was a poorly consolidated stoney/iron, anywhere from 1 meter to 5 meters in diameter, airbursting tens of kilometers up. Would love to know if anyone else saw it, when, trajectory estimates, etc. |
