Quiet aurora band - 10.11.2016 at 17.30 - 10.11.2016 at 18.00 Inari, Saariselkä Observation number 58292

Visibility II / V

Teppo Laitinen, Keski-Uudenmaan Altair

The forecasts showed that northern lights might be visible, so after dark I went to the yard to investigate the situation. The -18C ° temperature took the worst excitement to turn on the phenomenon, but I still got a few pictures taken.

    • Rays info

      The raysare parallel to the lines of force of the magnetic field, i.e. quite vertical, usually less than one degree thick light streaks. The rays can occur alone or in connection with other shapes, mainly with arcs and bands. Short rays are usually brightest at the bottom but dim quickly. The longest rays, even extending almost from the horizon to the zenith, are usually uniformly bright and quite calm, and unlike the shorter rays, most often occur in groups of a few rays or alone. Rays, like bands, are a very typical form of aurora.

      Artificial light pillars, which are a halo phenomenon visible in ice mist, can sometimes be very similar to the rays of aurora. Confusion is possible especially when the lamps that cause the artificial light pillars are far away and not visible behind buildings or the forest. The nature of the phenomenon is clear at least from the photographs.

      It may be possible to confuse such rays with artificial light columns. Compare the image below. Picture of Tom Eklund.

      There is no aurora in this image, but all the light poles - including the wide and diffuse bar seen at the top left - are artificial light pillars born of ice mist. Photo by Sami Jumppanen.

      Aurora and artificial light pillars. All the radial shapes in the picture above are probably artificial light pillars that coincide appropriately with the aurora band. In the image below, the aurora band has shifted and does not overlap with the pillars produced by the orange bulbs. There is no orange in auroras. Photo by Katariina Roiha

    • Band info

      Bands are usually narrower, more twisty at the bottom, brighter, and more active than arches. Bands usually develop from arches.

      Bands can form J and U shapes, sometimes even full spirals. The corona can also arise from bands. Bands are a fairly common form of aurora.

Kyllä kannatti kärvistellä pakkasessa,tosi upeat kuvat kuuraisessa maisemassa! Kuopion seudulla tulee lunta taivaan täydeltä! Revontulien näkyminen on kaukainen haave.

Kauniit kuvat. Puut antavat hienosti syvyyttä kuvalle

Hienoja. Kakkoskuvassa kaunis sommittelu ja puiden värit korostaa upeasti reposia!

Tosi hienoa jälkeä, upea tunnelma kuvissa. Ajatuksissakin narskuu pakkaslumi kenkien alla :)

Komeat kuvat. Pitäisi itsekin uskaltaa ottaa reposkuvia tuommoisessa suljetummassa tilassa. Yleensä sitä aina vain hakeutuu mahdollisimman avariin maisemiin.
