fyi,
Set of surface halos, the rare type visible here. It is two diffuse lines on both side of sun. I do not know the correct name of halo in english, in finnish it is referred as "Pinta-aurinkokaaret [Luomanen]" or "Luomasen kaaret". More info (in finnish) and simulation images, can be found by clicking "info" icon...

Thanks!
I was not aware of these surface halos. They seem to be categorized now as "surface helic arcs" (Schneeflächenhalo-Sonnenbögen)

and had been discussed before as "halo spokes" here
