A fireball in a twilight sky - 9.1.2018 at 08.08 Urjala Observation number 69413

Visibility IV / V


I stood at the bus stop and noticed a flash of a green-tailed ball on the low horizon. That Moomin and the tail star came to mind. There it dived behind the woods. I was terrified when I heard that really hard bang. I thought it hit the ground, but then I learned that it was most likely a supersonic bang.
