More on Faculae
Photosphere - luminous, apparently opaque layer of gases that forms the visible surface of the sun or any other star.
Faculae:
Faculae are bright granular structures on the Sun's surface that are slightly hotter than the surrounding photosphere. A sunspot always has an associated facula, though faculae may exist apart from such spots.
Faculae
Magnetically heated filamentary regions which appear near the limb of the .
Faculae
Faculae are bright areas that are usually most easily seen near the limb, or edge, of the solar disk. These are also magnetic areas but the magnetic field is concentrated in much smaller bundles than in sunspots.
Faculae
(a) Bright areas on the face of the Sun, commonly in the vicinity of sunspots. Named by Johannes Hevelius, they are thought to be caused by luminous hydrogen clouds close to the photosphere. They last on average about 15 Earth-days.

Faculae Unusually bright spots on the Sun's surface.
Finder A small telescope, ideally of wide field of view, that is fixed to the main telescope in order to facilitate the finding of objects.
FACULAE
Small regions of the solar photosphere that are a few hundred degrees hotter than average, and which therefore appear as slightly brighter regions.
Faculae
bright patches that are visible on the Sun's surface, or photosphere.
Filament
a strand of cool gas suspended over the photosphere by magnetic fields, which appears dark as seen against the disk of the Sun.
Faculae. Bright patches seen of the photosphere during solar observation.
Fireball. A very brilliant meteor.
Solar faculae are bright spots that form in the canyons between solar granules, short-lived convection cells several thousand kilometers across that constantly form and dissipate over timescales of several minutes.
FACULAE
Falculae are bright patches on the sun that are associated with or any region which is brighter than the surrounding area on a planet or a moon.
faculae A bright region of the photosphere seen in white light, seldom visible except near the solar limb. fault A crack or break in the crust of a planet along which slippage or movement can take place.

faculus (pl. faculae) - Bright region near the limb of the sun.
flash spectrum - The spectrum of the very limb of the sun obtained in the instant before or after totality in a solar eclipse.
faculae (NASA Thesaurus / NASA SP-7, 1965) Large patches of bright material forming a veined network in the vicinity of sunspots. They appear to be more permanent than sunspots and are probably due to elevated clouds of luminous gas.
ACTIVE REGION (AR) A localized, transient volume of the solar atmosphere in which PLAGEs, SUNSPOTS, FACULAe, FLAREs, etc. may be observed. AFRED Abbreviation for the A INDEX for Fredericksburg.
In the neighbourhood surrounding the penumbra the granules appear to be packed more closely, forming brilliant patches called faculae.

A glass filter that fits snugly over the aperture of a telescope and allows the photospheric surface of the sun — sunspots and solar faculae — to be observed comfortably and safely. A good solar filter blocks some 99.99% of the sun.
These are areas, which are cooler (4000 degrees centigrade) than the surface and so appear to look darker. Associated with sunspots are faculae that are characteristic bright regions, which precede the appearance of sunspots.
active region: An area of the solar atmosphere where the Sun's magnetic field is concentrated. The concentration and bipolar nature of the magnetic field results in the formation of dark areas such as sunspots and bright areas known as faculae.
