Ondanks dat we deze week in een meteorenregen zitten, ging het hier om een "sporadic".

A very bright fireball exploded over Lapland, northern Finland at 16:40 UTC (18:40 EET) on November 16, 2017. The event lasted between 5 and 10 seconds and was seen across northern Finland, especially Nellim, Solojärvi and Ivalo, and from northern Norway. This is 5th major fireball event within 48 hours, possibly 7th.
According to local media reports, a sonic boom was associated with today's event. "There was a loud noise after the lights went out and the houses shook," fireman Mauri Saniola Inari said, adding that the event was initially described as an aviation accident.
"The sound and light observations came from such a wide area that the location can't be determined," Inari said
The American Meteor Society (AMS) and International Meteor Organization (IMO) have so far received just 2 witness reports.
