Visibility III / V
I was driving south on e75 towards Oulu and just before Kuivasjärvi/Ritaharju turnoff I saw a very short fireball. I'd estimate it lasted about a second or two. I called a friend who was driving maybe 100 meters infront of me after a minute or so and he said he saw it too. I'm estimating it was 1/3 from the horizon and he saw it higher, maybe 1/3 from zenith. We made the call 19.26 according to phone records. It was a white bright ball with a yellowish tail with a trajectory to west, towards Kraaseli island. I would estimate due to the viewing angles of the two of us and just by general feeling of it that the phenomenon was not high at all, and clearly descending down from the sky.
An amazing sight and great experience. I'm glad to answer more specific questions if anyone is interested.
