a parhelion or mock sun; a solar halo. A parhelion is a very bright spot on the solar halo, sometimes rainbow-coloured. They tend to appear in pairs, above and below the sun or one at either side. They are not particularly common. As an article in the Aberdeen Weekly Free Press (1904) explains: It is somewhat unusual, I think, to see a “mock sun” on each side of the great orb. When one of these appeared, either before or behind the sun, the old folks spoke of it as a “fairock.” There was a rhyme about the “fairock,” which varied with its position in relation to the sun. The een it’s afore, [the one that’s in front] Ye’ll hear o’ no more, But the een it’s ahin [the one that’s behind] Ye'll shortly fin’. The article does not go on to say exactly what you might soon find, but it is safe to assume that it is not good. See Wadder-biter.
In Galloway, ferrick was used as a term for the solar halo itself.
