Auroras seen through breaks in the clouds - 8.9.2012 at 21.59 Kittilä Observation number 7780

Visibility II / V

Tapio Lahtinen, Tampereen Ursa

During the weekend's trip to Utsuvaara in Kittilä (Levi's igloo), the hope was to see the northern lights as well. Unfortunately, the wish came true for only 5 minutes as a faint gauze visible from the gap in the clouds.
Well, that didn't bother me because the views from the glass-roofed igloo were really stunning.
It occurred to me that that igloo would be an ideal (albeit expensive) place to spot even geminide star flights.

In the picture below, some sort of panoramic play about the accommodation. A bit of a kitchen is when hand composed of several images taken with a putty lens.

  Veil
  Veil is the most bland and very common form of aurora. It usually covers its homogeneous dim glow over a wide area of the sky at once. Most often, the veil is seen in the calmer and quiet phase of the night after the aurora maximum as a background for other forms. The veil can also occur alone and in that case it will be quite difficult to reliably identify as an aurora, especially at a observation site which has a lot of light pollution.
  
  A similar glow of light can also be caused by airborne moisture, smoke, or a very thin layer of clouds that reflects the light that hits them. However, clouds can also be used to identify veil, especially if the middle or upper cloud appears dark against a lighter background, then it is very likely to be aurora veil if the brightness of the background sky is not due to the rising or falling Moon or Sun. When photographing, very long exposure times usually reveal the green colour of the veil auroras.
