A fireball at night, as bright as a full moon - 25.11.2021 at 17.08 Kemi Observation number 102510

Visibility III / V


I walked north with the dog along the sidewalk south of Senior Park, maybe about 010-015. A very bright and rather large (about the size of a street lamp light, taking that short side of it) light ball flew really hard based on my own assessment in about 335-345. There were some middle clouds in the sky that obscured it from my view, in addition to which there was also a considerable amount of light pollution in the direction of flight. The ball of light drew a long and very bright line behind it. The whole phenomenon was visible for about a second. I work as an air traffic controller, and I would estimate the speed to have been at least several thousand knots, using fighters and their movement in the sky as a control.
