Sky camera observation of quite bright night clouds. With a darker backdrop, these would probably have been incredibly great. The first frame of the video (with no night clouds yet) is a 60 st maximum stack starting at 23.54 SKA, and the last at 02.53 SKA started.

Panu Lahtinen, Pollux, Aalto-yliopisto

The nicest avalanche I've ever seen. Visually goes even ahead of Sylv , although the pictures / videos are not as spectacular. The number of flashes (Discharge Channels) seen during the season doubled from one to two!

Tiavaskamera camera observation. In the first video a video composed of maximum stacks of 60 s, in the second approximately the same period so-called. of "magic stacks," i.e., average stacks minus the stack a couple of minutes earlier, and the end result stretched by linear fitting. The latter video also shows high twilight rays.

Upper-atmospheric lightning

12.6.2019 at 02.00 - 02.14 - Espoo (I)
Panu Lahtinen, Pollux, Aalto-yliopisto

MCS, who left Germany for a long time, was hooked after seeing Finland in the Baltics, so the chances of high flash were high. In the evening, though, it seemed that Cloudiness was blocking the observations, so I didn’t tune the sensible to shoot. However, the sky camera is constantly on, so after a little dodge of clouds, three clusters got caught, even though the contrast is really lousy. For all, motherfound candidates were found from either Blitzortung or the Finnish Meteorological Institute. Timestamps are in UTC time. The fourth image marked different cases to facilitate discovery. The f...

Image of an exceptional thunder cloud

16.5.2019 at 08.30 - 09.00 - Madison, Wisconsin, Usa (IV)
Panu Lahtinen, Pollux, Aalto-yliopisto

On the way to the bus stop, I noticed that there are some sets coming from the north. At this point, the cloud was not yet at its best, but when it was close the bus was already in the Urban Area and there was nothing visible between the houses other than flickering, sleet and heavy rain. A couple of lightning struck in less than a mile, but apart from heavy rain and small gusts, nothing really came to Madison. There seem to be some thousands of lightning locks in the lifetime of that MCS.
