Brilliant dashcam fireball videos help scientists find 3 meteorites in Slovenia

By diligently tracing dashcam footage from a particularly spectacular fireball seen over central Europe in February 2020, a team of scientists identified the possible source of the space rock.

The fireball, which appeared on Feb. 28 and 10:30 a.m. local time, was recorded by a handful of cameras spread across Slovenia, Croatia, Italy, Austria and Hungary. And the footage appeared to show a space rock breaking into 17 smaller pieces during an airburst event, when an asteroid survives the harsh passage through Earth's atmosphere but explodes before hitting the planets' surface.

Local residents found three pieces near the Slovenian city of Novo Mesto, weighing a total of 1.6 lbs. (720 grams). (However, the largest fragment seen in the footage — potentially 2 lbs. or 10 kilograms on its own, the researchers say — is not among them.)

In order to better understand the event, a team of scientists decided to piece together the footage to track the space rock's path to Earth. Usually, that would be accomplished by tracing a fireball's path across the stars — but this meteor fell during the day.

So the scientists recruited local residents to photograph the same landmarks that appear in the videos. Combining the fireball footage, the sky images and footage of a known light source filmed by one of the same types of cameras used on the fireball, the researchers were able to piece together a path for the space rock.

The path suggests that the meteor may hail from a near-Earth asteroid, although the scientists aren't sure.

Although the scientists were able to improvise ways to use the observations they had for the fireball, they'd prefer future meteors in the area do them the courtesy of arriving overnight, since central Europe is chock full of overnight cameras.

"The fireball's path is in a volume of the world's sky among the most densely observed by specialist night-operating cameras," Denis Vida, a planetary scientist at Western University in Toronto, Canada, said in a statement released by the Europlanet Society, at whose annual conference he presented the research on Tuesday (Sept. 21). "Its path would have been caught by at least 20 if it happened just a few hours earlier."
