A beautiful halo encircles the sun, while we descend and traverse the snowy southwest flank of Skardstind/2373m, the 5th highest mountain in Norway,
after climbing and summiting this prominent peak in the northern parts of Jotunheimen National Park.
Also note the two parhelic sundogs on either side of the sun. This atmospheric phenomenon is described in detail here: Atoptics.co.uk
The ring appears slightly distorted, due to its offset position from the frame center, and the ultra wide-angle optics used (AoV 114º).
