Some fireballs break into several fragments. For the second peak at 8 UT, viewing shoud be good in North America. However, there is a lot of uncertainty in this prediction.

If a meteor is sufficiently large, part of it may survive and strike the Earth, in which case it is called a meteorite.
Meteorites provide astronomers with useful information about our solar system.
Particularly prolific periods for meteors are called meteor showers. They typically occur at specific times of the year. The reason for this is simple. Certain regions of our solar system have high concentrations of debris. Each time the Earth passes through such a region during its journey around the Sun, a meteor shower takes place.
