Salamointia - 12.5.2011 at 21.45 Espoo Observation number 598

Visibility III / V

Kaverí reported that a small "red cell" would be approaching our whereabouts. Wefts around the neck and out with the dog. 3 minutes came first hailstones and then a strong flash in the cloud (n at 22.45), about n 2 seconds and a decent jolt followed by a rapidly fading rumble. An interesting sky when in the south direction was completely clear, the stars and the moon were just visible. Judging by the loudness of the sound, that might have been a ground flash as well, although I didn't see it as a flash with the "side eye", i.e. I didn't see the actual flash, so it was a bit of a guess whether it was just a cloud flash. At least the farmer and the wilderness magazine Sadetutka registered the attack in place at 11 pm in the radar picture.
