Visibility IV / V
I was visiting the yard when at about 00:16:30 the high sky flashed loudly, just like a flashlight or lightning, that is, really short. No sound was heard. The flash was, I think, facing west from the point of my observation. When I came in, I saw two more flashes around 00:45:00 and 00:46:30. There was cloudy and light snowfall at the time of observation.
What kind of light phenomenon could it be? Kalevantuli?
