One more shot of 5/6 November in Rovaniemi

This view shows several "rare white arcs". On the right the long spectral arc is 46 supra/infralateral arc. Towards the middle of the image from top to bottom are helic, subhelic and Wegener arcs. Diffuse and Tricker anthelic arcs are seen on the left and also weakly a patch of subanthelic arc. On parhelic circle blue spot is in the center of the photo.


  1. Thats a nice side-view because one can see how the arcs extend to the anthelic region.

    Keep up the good work.

  2. This point of view is very nice. And the fact that you were able to have some effective elevation for the lamp makes a huge difference!

  3. "46 supra/infralateral arc" It is the same name of

    `Parry supra- and infralateral arcs`?

  4. Parry supra- and infralateral arcs are from Parry crystals.

    46 supra/infralateral arcs are from column crystals.

    Yeah, I see why you are confused. We have messed up halo nomenclature pretty badly.

  5. thank's!

    it is clear now.
