      Form not identifiable
      Sometimes auroras have to be observed in such poor conditions that it is not possible to reliably identify the shape even if for example the structure and conditions could be recognized. Such a situation could be the outcome of for example alight background sky, cloud cover or a covered horizon.

  • Colors with unaided eye and other features
    • 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.

Tässä on kyllä jotain maagista. Hieno bongaus!

Olivatko nuo muodot ennen vai jälkeen alimyrskyn? Äkkiseltään katsottuna voisivat olla chorus-aaltojen luomia sykkiviä diffuuseja revontulia.
