(meteorobs) The source of the mega bolids of the past days?

[Roberto G.]

Perharps the source of the megabolids of the past days it's a torus of 
objects with orbits similar at this?

See the low inclination and the semi-major axis.

The 14 July and days around we could to see newly a number of big bolids.
It's possible that this object it's a framment of the Earth expulsed when
occured one ot the last big impacts? Perharps that of the dinosaurs!
Best greetings.
