Quiet aurora band

8.9.2015 at 02.54 - 03.04 - Helsinki (II)
Pentti Arpalahti

It did take a standstill when the oval glowed red, but the sky was before eleven in the morning. There seemed to be some flicker in the clouds, but nothing suggesting a repo came off the images. However, the sky became completely clear at three o'clock and the cell was able to catch a calm belt. Didn't get stuck anymore.

Mikko Blomqvist

At half past twelve I went outside to check the northern lights situation and half the sky shone green in the western sky. After midnight, towards midnight, the repos rose trembling high and fluctuated rapidly. The camera also showed a bit of purple, but it was not distinguished by the eye. Timelapse video can be found here:

There were autumn northern lights even in the southern sky, here in the northwestern sky.

Jorma Mäntylä

The handsome show was going when I came out after midnight. Even in the southern sky flickered. With the camera in shooting condition, the clouds began to cover the sky and little was visible from the cracks.

Even a hundred or so enjoyed the handsome northern lights. The wiser ones can tell if the proton arc is in the pictures or not.

In the diffused light of the agglomeration on the edges of the cloud front, a clear but dim northern light.

Tapio Lahtinen, Tampereen Ursa

The sky camera in the north of Tampere showed a belt rising quite high. At the same time, I took 3-minute exposures in the southbound direction on Tamron's telecon @ 70, which showed a lot of color like Revontule.

Northern lights in the northern sky. It looks like a strange cloud to the naked eye, the colors stand out well with the camera.

That's them, repos. Behind the clouds. Kajo seems to reach almost as far as Otava's bucket.

Aija Kaartinen

At first, a really dull gauze was visible, which brightened and seemed to turn more into an arc. Unfortunately, the clouds began to fill the sky at a point when the reposet was little activated. Pokkari isn't really enough for these pictures, but let me show you a few pictures as they stand.

Mikko Peussa, Ursa (Länsi-Suomi)

Cloudy and rather windy weather hampered the observation, but the northern sky was also very green, following the south as well.

Hardly from the sky when the northern lights predicted honey from the sky, and meteorologists clouded .... Well, we drove in the darkness of the night and looked for a suitable place to shoot. There were clouds everywhere, but here and there were open points lasting a few minutes. The car headed for the guy's cottage, where there happened to be a moment lasting in the clouds. Here is one picture of the catch of the evening, which was annoyingly small due to the clouds. Behind the clouds, he heated the green all night ...

Mauri Korpi, Lakeuden Ursa

Quite a nice northern lights show with a clear proton arc. Clouds eventually covered the show so that at 11.30pm the greenery was only visible from the small cloud holes to the west.

Karri Pasanen

An interesting and great play. At first, on Höytiäinen's shore, it already looked hopeless, a matched bush in front and completely covered the intense greenery visible from the crevices. On the way home, however, the sky suddenly became clear and stunning shapes were revealed from behind. When I got to the backyard, the arches and belts then went wild as a dancing crown on my head.

The northern sky pounded promisingly for a moment, but then the clouds rolled on again and the observation ended from this batch to it.

An interesting northern lights play. Right at the beginning an active radial belt, but then almost a couple of hours of lazy activity, mostly in the form of arches, which at best had three on top of each other. Finally at 11.20 pm the play was activated and there was a rather spectacular show on offer. The thing ended in pulsating spots and finally as the clouds covered the sky.

I watched from the northern lights camera that the horizon reflected promisingly, so I packed my stuff and went to describe the Milky Way in the field and wait to see if the repo ride would reach it - quite spectacular they grew from it around 23:00 and onwards. Edit: I dug and processed the other night's pictures in the hope of the proton arc and something along its lines had been left on my own cell - the maintenance will probably remove the spot if it seems that it doesn't meet the criteria. Figure 1 northwest at 9:39 pm, Figure 2 north at 9:56 pm, Figure 3 north at 10:02 pm, Figure...

Nothing was visible to the naked eye, but I took one picture for sure and it showed poor repos.
