Today was day of halos for all observers. I was seen: Parry arc, Infralateral arc. Martin Jankovic: Parry arc, 120 parhelia. Milan Cerny: Parry arc. Stepanka Kosova: Parry arc, 120 parhelia. Roman Manak: Parry arc and Martin Popek: 120 parhelia. For discussion: Lukas Shrbeny from Ondrejov had maybe Lowitz arc. You see his link.
