Now that's a display! There seems to be a brightening at the junction of 46° stuff and parhelic circle, but 44° parhelia would be located clearly inside 46° stuff. Am I missing something? Where is the subhelic arc?
I wondered too about the 44º. Not easy to say - Suspect brightening may be more the junction of pc and bright infra- and supralateral. Subhelic is evident on another image.
Nice display! Is the image with subhelic arc at the Internet?
I got wegener arcs and heliac on Jan 15th.
