All-sky aurora - 10.9.2018 at 22.00 - 11.9.2018 at 00.30 Kuusamo, Käylä Observation number 77496

Visibility V / V

Jani Päiväniemi, Ursa (Pohjois-Suomi)

Even before ten, the northern lights rose from west to east as an arc / belt over the zenith. I left for the beach and the arch was also visible to the north and the rays. At 10:43 p.m., corona lights developed in the belt passing over the zenith, which was a handsome revelation. After that, the sky was full if some looking shape and red, purple and even yellow were visible to the eye. The best set for this fall. The clouds began to increase and the gauze was full of sky, even in the southern sky an arc was visible through the clouds. At the same time, shortly before midnight, the disco lights also flashed for a while (pulsating auroras).

Additional information

Aurora brightness
- Bright auroras
Colors with unaided eye and other features
- Streaming auroras
  
  Streaming. In streaming aurora fast irregular variations in brightness occur along the horizontal dimension of homogeneous shapes.
- Flaming auroras
  
  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
  
  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..
- Yellow auroras
  
  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
  
  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.

Wauuuh !!!! ompas ollut komeaa tykitystä Kuusamon miehelle tarjolla ! Huikeaa kiehkuraa ja väritystä. Kaikki kuvat mielettömän hienoja..suosikkini 2 ja 4 kuva ! Olipa tuota latausta tarjolla eilisillalle kun katseli Auroras:Now.n ennustetta ja huima pudotus oli Sodankylän magnetometrin x komponentissa ! Onkohan tuo Sodankylän magnetometrin aika näin kesäaikaa 2 tuntia jäljessä paikallista aikaa täällä Suomessa..jospa joku asiaa tunteva tästä kommentoisi. Etelässä ois varmaan saanut näistä jotain irti mutta se kuuluisa pilvisyys täällä peitti taivaan !

Oijoi, kunnon tulet! Mahtava räpyläpari kutoskuvassa :)

Jani Päiväniemi - 11.9.2018 at 23.07

Kiitos Kari ja Tero kommenteista! Tosiaan jänniä muotoja syntyi välillä noihin tuliin. 2 kuvassa on mielestäni pääkallo ja 4 kuvassa omega merkki. Nyt vasta kun Tero sanoi räpyläpariksi kutoskuvaa niin, näyttää kyllä räpylöiltä:) . Tuli otettua satoja kuvia eilen, pitäisi katsella ajan kanssa läpi ne. Tuommoinen taivaan kattava näytös on vaikea kuvata kun ei tiedä minne päin kuvaisi kun joka puolella tapahtuu vaikka aika paljon tuohon 8mm kenttään mahtuu kyllä. Nyt sataa vettä ja saa nukkua rauhassa. Kuvauskelejä teillekkin toivotan

Myös Kuusamo on ollut paraatipaikalla. Kuviin olisin kaivannut lisää kirkkautta, mutta ei kontrastilla.

Kiitos Jukka kommentista. Oli hieno tykitys kyllä ja käytin aika lyhyttä valotusaikaa ettei pala kuvat puhki. Jäivät hieman tummiksi. Kuvat on suoraan kamerasta.
