A fireball at night, as bright as a cresent moon

10.9.2015 at 22.49 - Vesilahti (IV)
Jari Luomanen, Ursa (Länsi-Suomi)

We saw this pretty bright fireball just before it disappeared behind the trees. We were on the beach and at first I thought someone upstairs turned on the lights as the surface of the pier was clearly lit. I was just looking at the northern lights on the camera screen at the time, looking at the surface of the dock. I turned the camera as fast as possible in the direction of the clearly visible afterglow of the fireball, and I still got the smoke stick still recorded on the screen.

Diffuse glow

Very dim echo behind a thin gauze. It came out so well in the long exposure. Of course, it was also visible visually. I would have chosen gauze as the title if one had been available.

A little unfortunate I was in a bad place when the northern lights appeared in the sky. It was nice to see the fire for a long time though.

At first I noticed a calm northern lights belt for quite some time. Then I would go inside, naturally miss the brightest phase of the Northern Lights, and eventually only have time to capture the fading end of the show. The first image of the dim rays and the second image of the calm belt of the early stages.

This calm show seemed to last all night. The brightest stage involved some quietly moving rays and reddish tones. At half past four in the morning the fatigue prevailed and I stopped filming the fading fires. By no means a landmark play, but nice to watch visually as well. More pictures here .

Half-sky auroras

3.9.2012 at 22.01 - Tampere (IV)
Jari Luomanen, Ursa (Länsi-Suomi)

Really great northern lights for a little over ten minutes from 10:16 pm to 10:28 pm. Immediately after that, spending was much more modest. What was remarkable was the considerable speed of the northern lights - they moved from side to side in the sky quite quickly. The brightest and best repos for me since 2005.

Jari Luomanen, Ursa (Länsi-Suomi)

Really great and active repos. For a moment, these brightened considerably, and a fine shade of pink brightened at the bottom of the green belt. The brightness was so remarkable that the exposure that was going on at the time was clearly overexposed.

Auroras seen through breaks in the clouds

It was quite comfortable to see life from the cracks of the clouds. I wish it was clear.

Quiet aurora arc

Jari Luomanen, Ursa (Länsi-Suomi)

One of the best nights of the cycle for myself so far. At times the going was nice bright and the deep red tones were especially beautiful. Those reds were hard to distinguish visually so clearly, but the images they saw grabbed like a disease. The movement of the arc was very slow, for a long time it was seemingly completely immobile. There was a little more life in the rays. More pictures here: http://jari.pic.fi/kuvat/Atmospheric+phenomena+and+sky/Night+sky/

Quiet aurora arc

Jari Luomanen, Ursa (Länsi-Suomi)

Now for a little while it was quite nice to see you, very dim only. Had to be very well lit. Red wasn’t visible to the naked eye, my eyes didn’t have time to get used to the dark when I played with the camera screens and flashlight all the time when there was enough clear sky. It could have been "guessed" to be there (and in that red torch on the east edge it was obvious), but it would have taken a little more time to see properly. It was unnecessarily hectic as the clouds rushed from the north on top.

All-sky aurora

17.3.2013 at 20.05 - Tampere (V)
Jari Luomanen, Ursa (Länsi-Suomi)

A mute northern storm: I have never seen anything like it in its brightness and colors. Purple was knockout. The best moments lasted a very short time. At its wildest, it clearly reflected the colors of the northern lights.

A calm arc of northern lights and short-lived rays appeared for a moment to adorn the starry sky above the illuminating night clouds.

Quiet aurora arc

17.8.2013 at 02.11 - Kangasala (II)
Jari Luomanen, Ursa (Länsi-Suomi)

Late summer northern lights night EDIT: Add a wider caption especially for the first image (slightly updated version): As the Earth revolves around its axis, the stars appear to be moving in the sky. In long exposures, this rotation causes the stars to draw into wide arcs. The last shades of brown adorn the skyline and the arc of northern lights colors the sky above it. As a result of the light-scattering property of the atmosphere, the stars appear to brighten as they rise from the horizon. For the same reason, right near the horizon, their light is also strongly reddened. A total of 71 expos...

Jari Luomanen, Ursa (Länsi-Suomi)

The highlight of this play was around 11 p.m. Then a very intense and fast-moving belt appeared for a short time. For myself, this is clearly going to be second in this cycle right from March 17th. after the fireworks seen. More pictures: http://jari.pic.fi/kuvat/Atmospheric+phenomena+and+sky/Northern+Lights/

The second activation of the night was a little more modest, but the reddish rays captured the images nicely. More pictures: http://jari.pic.fi/kuvat/Atmospheric+phenomena+and+sky/Northern+Lights/

These fires ranged from dim to non-existent, but always at times even slightly brighter rays were visible. I didn’t let it depress because my camera has a feature like adjustable shutter speed.

Quite a spectacular northern lights show. A continuous red veil and rays on the zenith were the best part of this set.

Shortly before nine was a very active but short phase, then calmed down. They stood out comfortably despite the moonlight and light-polluting clouds.

For a moment, the play, which had matured into a nice brightness, danced calmly on the northern horizon. More of these!
