Active aurora band - 23.3.2018 at 22.14 - 23.3.2018 at 22.24 Kolari Observation number 73505

Visibility III / V

Yrjö Benson, Ursa (Helsinki)

Rarely do you get northern lights, moon, clouds and stars in the same picture. Behind a thin cloud curtain, the moon illuminates the clouds shaped by the wind. The Northern Lights are so powerful and the moon is just right behind the gauze so that the moon is not too bright and does not spoil the visibility of the Northern Lights. Even a few stars appear and the moonlit one acquires the image at the bottom. There are no lights or diffused lights in this place, which is a great place to photograph northern lights. The Northern Lights are in the shape of a tension, like a whirlwind, and the shape of its left edge combines in some peculiar way with the shape of a cloud shaped by the wind. The shooting direction is to the southwest, in which direction this place shows fire quite often. The most common direction of skies is north-northeast. Moderate image processing, the image is as close as possible to what Lapland looked like at night.

      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.
