Aurora rays

1.4.2023 at 01.00 - 03.00 - Kempele (III)
Marko Haapala

Finally, after midnight, it cleared up and the arch appeared in the sky and a moment later again in a familiar spot within walking distance from home. Dim or bright northern lights at their best, find out about it again as a layman. Of course, the ski slope lights are on and the slope maintenance is in progress. Of course, it offered a new visual look to the already familiar perspective. Finally, the lights went dark and the normal mood continued and the rays of the aurora borealis were short-lived. The best seemed for a moment to be there in the direction of Oulu's light pollution and the...

Emma Kokko

Having missed yesterday's blaze, I went to try my luck for today. They only stood out to the eye for a moment. I was there for about an hour. On the horizon, the only thing standing out was the stationary green arch seen in the pictures. The rays appeared a few times, they had a purple color. I must have been late, I must have been quite shy when I arrived.

Aurora rays

30.3.2023 at 23.00 - Savonlinna (II)

I noticed a brief repos when it was a clear night. The moon hindered visibility, but with the naked eye a reddish color (purple in the picture) could be seen with the naked eye in addition to the green.

Maritta Kinnunen

Last week's northern lights were completely invisible due to the multi-day fog. There were few even now. It was clear at first, but soon thick clouds started to gather. As luck would have it, they were less frequent in the northern direction. At first, dim aurora borealis was visible and a very small mist like snow was falling. Suddenly, a strong green hue began to appear. It even looked blueish in the beginning and later too. For a moment, two different red colors were also visible. Oh that :) I've never seen such colored pillars or long rays before. I don't have much experience w...

Vesa Puistovaara, Porin Karhunvartijat

My attention was drawn to this rather spectacular spike that appeared at ~23:00, with red and purple colors. A great revelation, I think.

Terhi Törmälä

I wanted to rush to the game sites last night when I noticed that there is enough activity here all the way to the southeast. I was late for the start of the substorm, through the windshield of the car I could see how the green waves traveled in the sky. But there was still something left to describe. Beautiful red and purple rays and pulsating northern lights. And the supreme blue aurora borealis. For a moment, a pink lower edge was visible somewhere far to the north (second picture). For a moment, the rays rose up to the North Star. After the exposure, the clouds started to roll out and at t...

Markku Ruonala

Due to other commitments, I came to the observation site when the noise was already on. After last week's amazing set, this one didn't seem strange. In reality, however, this was a decent play, there was structure, colors and brightness, the movement was the only modest element.

Momentarily bright and colorful northern lights. Then clouds covered the sky. Always as impressive to watch and photograph. :)

Timo Nevala, Ursa (Länsi-Suomi)

I was looking at the moon with binoculars when the northern lights started to appear. The object of observation immediately changed to them. It was such a short "burst" of northern lights that lasted about an hour, the most active phase not even that. I probably wouldn't have seen it if I hadn't already happened to be in the yard looking at the sky with binoculars. The aurora borealis rose at its strongest almost to the zenith. The green color was momentarily very clear and strong even when seen with the eyes. The clouds were moving in the sky, sometimes disturbing. There were probably...

The aurora borealis is a model of light pollution in Turku, they were visible for a short while before disappearing again behind the artificial lights. At 11 pm, clouds covered the sky

Half-sky auroras

Tuija Liunala, Ursa (Itä-Suomi)

down in the sky a bright green arc above which all kinds of rays across the sky up to the moon. the density number was not perfect and the bright moonlight consumed visible colors, but from time to time even pink rays were visible to the eyes.

Timo Alanko, Vaasan Andromeda

The northern lights of the night in 1.27 min timelapse. The most active phase seems to have been at 11 p.m., but after a calmer period that followed, the fires started again and continued until dawn. Unfortunately, the OsmoAction fisheye lens still hasn't arrived. The video is composed of vertical images to include the zenith. Something like Corona would have been available. https://youtu.be/4Uostf4aCbg

Maria Akolahti

That's how it happened, that I got out of bed, in my night clothes, almost straight into the yard under 30 seconds, when I went to check to see what the situation was. First a very calm curve, then the life of the little one, a little break and then it was already a decent screen for a moment. At the same time, I tried to adjust the camera, the camera stand and the phone case. Here are a few pictures from the middle of the light pollution. A few funny moments were only recorded on the retina.

Taisto Komulainen

The last aurora borealis of March shone handsomely in the glow of the moon. In Kajaani, I photographed on the ice of Nuasjärvi. On March 30, 2023, the evening hours were spent in a frenzy in the snowdrifts, wading in a sweat looking for shooting locations.

A handsome setting moon and the Aurora Borealis at 23 degrees below zero, that's a fantastic combination for night photography in Kajaani's Paltaniemi from Eino Leino's house, looking in the direction of Oulujärvi

Diffuse glow

25.3.2023 at 23.00 - 00.00 - Nurmes (I)
Eero Karvinen

Proton aurora borealis in the southern sky. These are formed when the fast plasma of the substorm plunges into the inner magnetosphere. In the region of the ring current, the pre-existing cold and dense plasma reacts with the hot, kinetically energetic plasma to form EMIC waves. The EMIC waves then cause the protons to plunge into the upper atmosphere, and thus diffuse, slightly blue-refracting patches are formed in a significantly southern location compared to the normal oval. The light streak in the picture is, on the other hand, artificial light. #diffuusi
