Patchy white light blotches in the photosphere (not visible in H-alpha), usually seen mainly towards the limb due to limb darkening. Faculae are most often found near active regions or where one is about to form, and can last well after the sunspots in the active region have decayed (best seen in blue light).
Areas of increased brightness on the surface of the sun. Contrast to sunspots.
are irregularly shaped unusually bright patches above the solar disc generally associated with sun spots. They are active regions in the photosphere and have their equivalent higher in the atmosphere as chromospheric plages and coronal condensations. (Chromospheric calcium plages are sometimes called flocculi.)
Enhanced bright regions best observed near the Sun's edge.
an area on the surface of a star that appears brighter by comparison to surrounding regions
Bright regions of the photosphere visible in white light near the limb of the Sun. They are brighter than their surroundings because they are higher in temperature and density.
Unusually bright spots on the Sun's surface.
A bright region of the photosphere seen in white light, seldom visible except near the solar limb.
Falculae are bright patches on the sun that are associated with sun spots or any region which is brighter than the surrounding area on a planet or a moon.
Irregular patches of bright material present in the solar photosphere forming a veined network in the vicinity of sunspots. These regions are a few hundred degrees Kelvin hotter than their surroundings. They have low contrast on the solar disk and are best observed near the solar limb. These features relate directly to plage or brightenings in the overlying chromosphere.
These are brighter patches of the Sun's surface. They are often seen near sunspots. They are best seen near the edge of the Sun because they contrast better with the apparently darker limb. They often herald the appearance of sunspots and may be present after a sunspot has subsided. Some faculae are seen in high Solar latitudes and are not associated with sunspots at all. Also associated with faculae are plages or flocculi - clouds that are high in the chromosphere. These are apparently best observed in light emitted by ionised calcium.
