A fireball in a twilight sky - 16.10.2021 at 18.35 Helsinki Observation number 101821

Visibility III / V

Daniel Backström, Ursa (Helsinki)

Coincidentally, a fireball was visible between the two buildings for less than a second in the northeast-east direction. The fireball brightened and faded within a very short time. I recognized it as a fireball because of its high speed.
