(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).
(1) Bright region of the Sun's photosphere. Faculae can occur anywhere on the Sun, but the largest faculae are found near sunspots. (2) A bright spot on a planet or moon.
Unusually bright spots, or patches, on the Sun's surface. They precede the appearance of sunspots and can remain for some months afterwards.
Brighter-than-average regions on the Sun’s surface that typically appear near a group of sunspots just before the sunspots themselves appear.
A circular to subcircular region which is brighter than the surrounding area.
A facula (plural: faculae) is literally a "bright spot." It is used in planetary nomenclature for naming certain surface features of planets and moons, and is also a type of surface phenomenon on the Sun.
