All-sky aurora - 8.9.2017 at 02.00 - 8.9.2017 at 03.00 Rovaniemi Observation number 66860

Visibility V / V


I drove to Luosto in the early evening to describe and wait for the X9 flare CME predicted to arrive. Location old familiar Orresokka. The first northern lights were already visible at 10.30pm, albeit dim due to the full moon. From time to time, however, they intensified until they dimmed again, and again it occurred to me that here they were again.

Little by little the clock was moving towards midnight and the dim arc seemed to rise and rise and eventually move south of the zenith until at 1 o'clock I decided to leave.

At 1.30 I still stopped at the jagged edge after the Luosto holiday and watched when the ribbon in the southern sky was relatively clear, however, I had seen a similar effect in the northern lights on February 16, 2016 (even then it was a full moon). I don’t know if anyone reads this stuff, but nonetheless, I continued on my way home.

Until then, after about half an hour of driving, the sky actually flashed, the car on the side of the road and after taking a couple of pictures, I found that I couldn’t take pictures of these at this location this time, so I caught my lens and shot a video. The show lasted about ten minutes, and the journey continued.

And again I had to stop closer to Rovaniemi, where there were better conditions for filming. This show lasted again for about 10 minutes, after which the sky went so far into the cloud that now finally towards home.

Additional information
  • Aurora brightness
    • Very bright auroras
  • Colors with unaided eye and other features
    • Streaming auroras info

      Streaming. In streaming aurora fast irregular variations in brightness occur along the horizontal dimension of homogeneous shapes.

    • Flickering auroras info

      Flickering. This rare subclass refers to a situation where irregular variations in brightness occur in aurora, such as in fluttering flames.

    • Flaming auroras info

      Flaming. This rare subclass of aurora does not mean so much a single shape, but a large area in the sky. In the flaming aurora, bright waves that are sweeping upward towards the magnetic zenith emerge in the sky. Very rarely waves can wipe downwards. Bands are usually reported during flaming, less often spots.

    • Pulsating auroras info

      Pulsating aurora. The brightness of the pulsating aurora usually varies rhythmically over a period that can be only a fraction of a second at its fastest, but can also be several minutes. Pulsing usually only occurs in(strong auroral conditions) higher quality shows , especially towards the end of them. However, the pulsation may be followed by yet another eruption. Sometimes the variation in brightness is at the same stage in the whole form, whereby the whole form "turns on and off" at the same time. Pulsation is also found in arches and bands, but above all in spots..

    • Blue auroras info

      Clearly blue auroras can be seen only during the best aurora displays close to the maximum phase or soon after it. Sometimes blue auroras can be seen shortly after the sunset at the top part of the auroral shapes, specially rays. It is created by the mission of the ionized nitrogen molecules created by the suns radiation.

    • Yellow auroras info

      Yellow aurora color that can be seen with naked eye is a rarity that can arise from suitable combinations of green, red, and blue in bright shows.

    • Red coloration of the shapes lower edge info

      Red lower edge visible with the naked eye. The bands which are starting to level up their activity and are green colored have quite often a narrow red lower edge. This is the most common form of red color which is derived from molecular nitrogen.

    • Green auroras info

      Green, seen with the naked eye, is one the most common colors of the aurora. The green color is derived from atomic oxygen.

    • White auroras info

      Paljain silmin valkoinen väri näkyy useimmiten himmeissä näytelmissä, kun silmä ei kykene erottamaan mitään varsinaista väriä. Harvoin kirkkaissa näytelmissä valkoinen väri voi myös syntyä sopivista vihreän, punaisen ja sinisen yhdistelmistä.

    • Violet auroras info

      Usually in Lapland or even in the south you can see purple auroras in stronger aurora shows. The most common color in auroras along with green and red.

Näytti tuo kotkasi liitelevän kansainvälisellä sivullakin:) Upeaa jälkeä tekee nykyjärkkäri videollakin. Sony ei tullut mukaan teknisiin tietoihin?

Ykköskuva on kyllä nappiotos. Voisi kuvitella, että on vaikea suunnata kameraa, kun joka puolella taivasta tapahtuu yhtä aikaa :-)

Hienot kuvat taivaantulista! Upea video! Siitä näkee hyvin,että on todella koko taivaan revontulet!

Kari Rytilahti - 11.9.2017 at 19.43 Report this

Komeat on reposkuvat ja upea video!  Mikä Sony millä olet videon kuvannut ja kertoisitko millä asetuksilla ? Itsellä Sony A 7 S ll  ja Zeissin 20 mm F/2  lisänä Sigman sovitin Ganonin objegtiiveille.  Lisäksi vielä Atomos Ninja tallennin. Viime Jouluna Pyhällä ekan kerran testasin revontulivideon kuvaamista kyseisellä paketilla.

Kiitokset!

Video on kuvattu Sony A7S I:llä ja Tamron 15-30mm f2.8 objektiivilla adapterin kera. F taisi ollai 3.2, jostain syystä en saanut sitä täydelle aukolle laitettua, ISO 51200 muistaakseni. Atomos on itselläkin hankintalistalla, valovoimaisemman linssin kera.

Video tosin on editoitu facebookille paremmin sopivaan muotoon 720p ja bitratea myös laskettu huomattavasti alemmas.

Erikoisia revontulia ja hyviä kuvia! Videolla näky kyllä hyvin revontulet! Sony tais tehäkki a7 sarjan video kuvausta varten ja erityisesti hämäriin ja tässä tapauksessa pimeisiin olosuhteisiin.

Ihan hurjia, huhuhuh! Mahtavat kuvat ja upeat tulet! Tuollaisia kun joskus pääsisi näkemään...
