1. None actually saw the entry of the bolide, but all saw the flash of the explosion.

2. Atmospheric entry of the bolide A cosmic object entering the atmosphere loses its kinetic energy through deceleration and ablation.

3. Magma activity and bolide effect are also announced accounting for the occurrence of PETM.

4. Catastrophic fragmentation Catastrophic fragmentation is a likely means of producing an atmospheric explosion of a bolide.

5. It is thought that Electrophonic sounds may be induced in events of bolide, very bright auroral display, nearby strong lightning, earthquake and nuclear explosion.

6. So far the sighting of a such a bright bolide meteor, produced as a space rock is vaporized hurtling through Earth's atmosphere, really is a matter of luck.
