Faculae

Faculae are bright streaks visible on the surface of the sun. They are more obvious near the edge of the disc, the photosphere showing up less brilliantly. Facules are simply heaped up masses of the luminous matter forming the photosphere, and may be sometimes recognised as such when passing round the edge of the sun's disc. They are generally abundant in the neighbourhood of sun-spots.
