Hello halo watchers,
I did a simulation of the Jamsa display and by
looking at the gap between the lower sunvex parry
arc the lower tangent arc the elevation of the
moon is 30 degrees. In the last few images
showing the parhelic circle and subhelic arc
there appears to be a horizontal piece of a
colored halo near the ground and I think it could
be a lower wegner arc because the sky was full of
crystals.
When I get jpeg versions df the simulations done
I will email them.
Best,
Michael
