Planetary scientists are working to determine the origin of a vibrant fireball seen over Scotland, Northern Eire and northern England on the night of 14 September.

The spectacular occasion, noticed at about 10pm native time, was caught in quite a few movies on social media, which confirmed a stunning whitish-green gentle transferring at pace throughout the sky, in some circumstances with a path of glowing materials behind it.

On the time of writing, round 900 eyewitness accounts had been submitted to a global catalogue of fireball occasions maintained by the American Meteor Society and the Worldwide Meteor Group. Some observers even reported listening to a rumble following the occasion, which preliminary evaluation suggests occurred over a area close to the islands of Islay and Arran in Scotland.

It isn’t but clear if the fireball was the results of a meteoroid – a pure house rock – getting into Earth’s ambiance and changing into a meteor, or the re-entry of a chunk of particles from human house exercise, though early proof does level to the latter.

“There’s a moderately excessive probability that that is house junk, sadly. [The fireball] had a really shallow entry angle, a considerable quantity of fragmentation, which is typical of house junk, and it seems to be slowish. House rocks are typically a bit sooner. Nevertheless, we’re nonetheless crunching the numbers to get a superb estimate on the rate which can inform us for certain whether or not that is house rock or house not,” says Luke Daly, a planetary scientist on the College of Glasgow, UK, and member of the UK Fireball Alliance.

“Meteors sometimes enter the ambiance at very excessive speeds, 75 to 80 thousand miles per hour,” says John Maclean on the UK Meteor Community, whose cameras captured the phenomenon. This is able to equate to between about 121 and 129 thousand kilometres per hour. “House junk can be a lot slower, at possibly 25 to 30 thousand miles per hour relying on the unique orbit velocity.”
