Seems like the rare halos keep coming. While visiting my brother and his family I was outside his house watching this halo complex evolve. In terms of rare halos I got parry, 120d parhelia, Wegener arcs, blue on parhelic circle. While enhancing pics and I saw it in pics afterwards an inverted V shaped arc outside the parhelic circle. Could this be hi-sun Tricker arc?
Marko Riikonen what do you think?
