Upper-atmospheric lightning

25.9.2020 at 23.30 - 00.45 - Mäntsälä (II)
Paavo Korpela

September 24-25 there were thunderstorms quite abundant compared to the season. The thunder continued on 26.9. even the night before. 25.9. late in the evening I set out to see the shores of a nearby lake for distant lightning strikes on the western horizon. The sky was almost cloudless. According to the locations, the thunderstorms were about 200km away from my observation site. In the dark autumn night, faint flashes appeared as if from time to time. Circumstances called autumn night perpetuation, the starry sky and lightning reflections made the situation quite inspiring. On top of all that...

Half-sky auroras

I noticed the northern lights at night, when an active northern lights belt and rays were visible. When I went out to photograph the northern lights, at best they filled about half of the sky (the zenith also showed northern lights), but gradually became more vague and dim. I didn't have time to the scene in time for the northern lights. The shutter speeds I used were 10-20s, so the northern lights appear brighter in the images than they actually were. At the moment, only a slight reddish / purple hue stood out to the naked eye.

On the coasts of Estonia and Hiiumaa, lightning rarely. For the most part, only distant reflections were visible, but when the cloud curtain in front finally gave way, a few more bright lightning flashes were visible from the thunderclouds about 100km away. I also tried to grab fairy flashes against the starry sky, but failed.

There was a spectacular lightning strike at 3-4 o'clock at night in a deaf strip on the west and northwest sides of Helsinki. The deaf tape would go so close to my spot that the rumbles were heard. The lightning continued after 4 o'clock, but my distance gradually moved towards Hyvinkää.

The expedition of four bongars bongasi show thunderstorms in a great place of observation, which will probably have to be visited again. For a long time, the lightning bolts were admirably visible, there were also spectacular cb lamps at the beginning. However, the lightning faded somewhat around our observation site before we received the thunderstorm tape. The discharge channels were also a bit searchable.

Thunderstorms dimly lit by the moonlight and lightning flashes in the dark night of August .. A memorable experience, although the lightning intensity was not particularly good from my point of view. The tall cumulus clouds illuminated by the sunrise were also a handsome sight!

After a hot day, the only cloud in the evening sky was a handsome thundercloud visible on the horizon, located in Pertunmaa, ie about 115-120 km away. Based on the lightning locations, most of the lightning strikes between 20:00 and 20:30. Pictures are taken between 20: 06-20: 15.
