bolide

We call these fireballs or, more technically, bolides, and they can emit enough light to cast shadows.

It was also a massive learning experience for scientists, the largest atmospheric impact since the Tunguska bolide in 1908.

The meteor - sometimes called a bolide for its particularly intense brightness - could be seen by much of southern Norway.

The fireballs that explode in a bright terminal flash, often with visible fragmentation, are known as bolides, according to the American Meteor Society.

Mr Kacerek said: "Daytime fireballs are extremely rare. It has to be a very large bolide class, to be visible during day."
