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.)
