Good northern lights again

19.9. September has been favorable in terms of northern lights. The third bigger show of the month arrived on 18/19.9. Sightings have arrived from the entire length of the country, from Enontekiö to Helsinki. Attached are Hanna Kanniala's and Mikko Lemola's pictures of Ii and Kouvola.

A fog arc in Hämeenkyrö

19.9. Mervi Ketola photographed an exceptionally spectacular arc of fog on Hämeenkyrö's Heinijärvi on Sunday. The series of images shows that the fog started to recede from behind the photographer. This is the optimal situation for the creation of a beautiful phenomenon when the sun shines brightly into the fog ahead.

Northern lights on the night before Wednesday

13.9. Apparently, the cloudiness situation dictated that observations of this display have only been east-oriented. In addition, one photo set has also come from Karigasniemi in the very north. Attached are pictures of Antti Taskinen and Jussi Koponen from Joensuu and Kuopio. A few observers also pointed out the mild weather for the time. "It was still warm at midnight, 18 degrees, and the lenses of the cameras didn't fog up at all," writes Petri Martikainen , who filmed at Juva.

September epsilon Perseids

11.9. The lesser-known September epsilon Perseids produced 13 tracks in the images of Harri Kiiskinen's camera on 8/9.9. at night. Parva had eruptions in 2008 and 2013, where many bright shooting stars were seen within a few hours. According to Esko Lyytinen's modelling, the next stronger maximum is not in sight before 2040, but since very little is known about the swarm, IMO it is worth keeping an eye on.

Nice lights. Fog and clouds hindered visibility a bit. I mostly watched and let the camera click. It was difficult to capture the dim, pulsating lights of the after-show, but now I think I somehow managed to do it.

Petri Martikainen, Ursa (Itä-Suomi)

The magnificent aurora borealis all over the sky started as soon as the sky got dark. For a long time, the green cloud covered almost the entire sky and most seemed to be happening directly overhead. Several cameras shot timelapse in different directions, there was also something to shoot in the south direction. Figure 1. "Aurora borealis bubble" facing south at 22:56-00:29. Figure 2. Full sky at 21:18-22:04. Figure 3. Eastern sky at 22:22-22:57. Figure 4. Eastern sky at 20:56. Figure 5. Western sky at 21:32. Figure 6. The whole sky at 21:55. Figure 7.

CME again offered quite a spectacle. The cloudiness posed freezing challenges and it was up to the smallest detail so that the whole spectacle would not have been seen. The northern lights were currently spreading across almost the entire sky, offering in addition to green, red and pink hues visible to the eyes. One special feature was the so-called auroral streamer, which on the north side of the oval provided an arc-like stringy area like a substorm. Blue was also visible with the naked eye for a while in this area. In the bottom picture, these blue-toned threads. After the substorm, the sky...

The northern lights were muted due to the cloud cover. But such a light phenomenon was recorded. I'm not sure about the phenomenon. A car? Fairly long-lasting: squares 8 s, gap approx. 2 s.

I photographed the northern lights in Rusko and Turku. At the same time, my old camera filmed a series by itself on the balcony at home. I put together such a quick (approx. 6 seconds) gif animation from those pictures from 23:00 to 23:30 at the end.
