Visibility III / V
With the help of Hollola's observation, I found this in the recordings of my north-facing camera. You can't see much of that from behind the birch in the yard, but hopefully it will help when defining the flight path. If it's the same fireball, it went much further north than it looked from Hollola. The flight direction was not marked there, so it will be interesting to hear if it matches in those respects. Camera time around 05:34:30.
