Visibility III / V
According to the Finnish Meteorological Institute, it has been completely cloudy, so the fireball could have been very bright. On the other hand, the camera is quite sensitive to light (you can see stars in a cloudless sky), so the fireball may appear brighter than it would have appeared to the naked eye.
I couldn't set the flight direction on the iPad using the Safari browser.
Update:
I replaced the original video, because in the video of the camera you could hear the sound of a bang approx. 7 seconds after the flash. In the new video, I edited the volume of the sound so that the bang is heard. Nevertheless, the volume should be turned up. The screenshot from the editing application shows the bang as a curve in the place I circled in yellow. If the bang came from a fireball, it was only approx. 2km away. Did the fireball explode or was there a supersonic boom!?

Melkoinen välähdys. Hieno havainto pilvisellä tai sumuisella ilmalla.
Noin pian tulipallon jälkeen kuulunut pamaus ei voi liittyä tulipalloon. Paineaalto etenee äänen nopeudella ja yleensä yliäänipamauksen osuminen maanpinnalle kestää puolesta minuutista yli minuuttiin ja silloin pitäisi olla suoraan tulipallon alla.
