(meteorobs) DFW event

[Pat]

I would love the coordinates and altitude of the Edgewood hit!!!
Based purely on the sonic footprint and the approach angle from the police dash cam. I put it about 40-60 miles due east of Ennis. But I think it is a little farther east and maybe a little south of that.
Some of that is likely because there are so many more people in the Dallas area to hear it.
Based on many "double boom" reports and at least one knowledgeable man listening for the boom who heard about 4 mini booms just after the main. I estimate it was breaking apart at about 120-130,000 feet. There were at least two main pieces (likely 4-5) between 30 and 80 feet from each other at that time. So it is likely a fragile bolide. Based on that it should not have made it past the Tyler/Jacksonville line. But there are many reports east of that and even one from Keachi LA. Surprising very little from Henderson and Carthage, so I am guessing it went dark long before that. People in the fall zone would not likely hear it. It would also be less noticable coming at them and looking like it would pass over them, but burn out west of them. Someone from Beckville captured on their house security camera, which I am guessing was facing west. I sent them an email asking for details of the angles. KETX in Tyler has a doppler radar...maybe we can get more from it.

I've examined all the nearby radars and I'm somewhat surprised and disappointed to say that I don't see anything convincing. I'm not done looking, but by all indications from the fireball this one should have been obvious.

There's also a series of returns near Allen on the Fort Worth NEXRAD that interest me. They appear at the right time and populate a series of elevation scans, but they appear to linger too long - a full half-hour - without moving.  They act more like a ground reflection or an interference source than meteorites.

It looks to me that it generally followed I-20 and generated a swath of sonic booms in the eastern end of the DFW metroplex. That tells me that any fall site is either in that area or just to the east of that area, which is where I've been looking.
