(plural, faculae) -- A bright region near a sunspot, as observed (usually, only near the limb of the Sun) in photospheric images. If observed in a chromospheric image, it would be referred to as a plage.
a large bright spot on the sun's photosphere occurring most frequently in the vicinity of sunspots
A bright cloud-like feature located a few hundred km above the photosphere near sunspot groups, seen in white light. Facula are seldom visible except near the solar limb, although they occur all across the Sun. Facula are clouds of emission that occur where a strong magnetic field creates extra heat (about 300 degrees K above surrounding areas).
