One of Sol's more common manifestations, it takes a golden drawing of an eye in the air, with a sea of fire within it, and a golden sun for an iris. Sol usually manifests his left eye, or both eyes together against a backdrop of fire.
Unlike Z, who has one main symbol, Sol generally has several. The symbol is generally an eye like symbol, with the symbol of fire within in it, but also sometimes light, depending on that cultures, opinion/experience with Sol. Generally these cultures have mainly, or only see Sol's eye manifestation and the symbol is meant to represent him as they understand him.
There is, however, a main mark which Sol would commonly use to sign things. It is his common eye design, but with the iris taking the form of a star mark.
