Blazing fireball lights Arctic sky, glowing like ‘100 full moons’

COPENHAGEN, Denmark — A blazing fireball lit up the dark skies of Arctic Finland for five seconds, giving off what scientists said was “the glow of 100 full moons” and igniting hurried attempts to find the reported meteorite.

Finnish experts were scrambling to calculate its trajectory and find where it landed, according to Tomas Kohout of the University of Helsinki’s physics department, who said Thursday night’s fireball “seems to have been one of the brightest ones.”

It produced a blast wave that felt like an explosion and could also be seen in northern Norway and in Russia’s Kola peninsula, he said.

It might have weighed about 220 pounds, according to Nikolai Kruglikov of Yekaterinb­urg’s Urals Federal University.

“We believe it didn’t disintegra­te but reached a remote corner of Finland,” Kohout said.

The Norwegian meteorite network said the fireball “had the glow of 100 full moons” and likely was going northeast, perhaps “to the Norwegian peninsula of Varanger,” north of where the borders of Russia, Finland and Norway meet.

Kohout said scientists looked forward to any space debris they can get their hands on. “This is a unique opportunit­y to get otherwise inaccessib­le space material.”

Viktor Troshenkov of the Russian Academy of Sciences said that the fireball could be part of a prolific meteor shower known as the Leonids, which peaks at this time of year. He said he felt Thursday’s fireball likely wasn’t the sole meteorite but others maybe were not seen due to thick clouds elsewhere.

Troshenkov told Tass that meteor showers can be even stronger. The Leonids reach their maximum once every 33 years — and the last time that happened was in 1998, he said.

In 2013, a meteorite streaked across the Russian sky and exploded over the Ural Mountains with the power of an atomic bomb, its sonic blasts shattering countless windows and injuring about 1,100 people.

The 2013 Chelyabins­k meteorite was estimated to be about 10 tons when it entered the Earth’s atmosphere at a hypersonic speed of at least 33,000 mph. It shattered about 18-32 miles above ground, but some meteorite chunks were found in a Russian lake.
