Hi, Jarmo [or should I say "Master" ;o) ]
I hoped someone could help me on this anthelion pillar on the 9th Nov. It
was
my first Anthelion observation!
There was nothing like a parhelic circle, nothing like a sharp arc at
anthelion. Barely this spot, 3 to 4º vertically (yes it is small, I called
it
pillar because it was more vertical than horizontal) and 1 to 2º
horizontally
(unfortunately, these values are from my memory only, I had no camera at
hand
that day).
And since sun was low, observation was not easy, with trees and buildings.
Supra-Lateral Arcs were also my first ones. They were indeed very
colourful,
even if not very bright. Not joining at the top because too faint on that
part.
Infra-Lateral Arcs not seen. No trace of Circumzenithal Arc.
Greetings to you and to all,
Pascal
