APOD: Fireball over Iceland (2023 Sep 16)

Post by APOD Robot » Sat Sep 16, 2023 4:05 am

Image Fireball over Iceland

Explanation: On September 12, from a location just south of the Arctic Circle, stones of Iceland's modern Arctic Henge point skyward in this startling scene. Entertaining an intrepid group of aurora hunters during a geomagnetic storm, alluring northern lights dance across the darkened sky when a stunning fireball meteor explodes. Awestruck, the camera-equipped skygazers captured video and still images of the boreal bolide, at its peak about as bright as a full moon. Though quickly fading from view, the fireball left a lingering visible trail or persistent train. The wraith-like trail was seen for minutes wafting in the upper atmosphere at altitudes of 60 to 90 kilometers along with the auroral glow.

Very cool. I was confused about why the mouse-over image showing the fireball had a much brighter blue sky, but the linked-to video revealed that it was the fireball itself that lit everything up!

I was confused as to why the ground did seem to be lit up by the fireball. I guess it wasn't bright enough for that.

It was nothing like the Chelyabinsk meteor, in other words!
