Plage. An extended emission feature of an active region that exists from the emergence of the first magnetic flux until the widely scattered remnant magnetic fields merge with the background.
PLAGE - Bright cloud-like feature found around sunspots that represent a region of higher temperature and density within the chromosphere. Plages are particularly visible when photographed through filters passing H or Ca spectral lines.

Plage
The bright rim of a sunspot, observed in emission in monochromatic light of some spectral line (H[alpha] or Ca II). It is a chromospheric phenomenon associated with and often confused with a facula. (sometimes called flocculus) ...

Filaments and Plage
Filaments are dark, thread-like features seen in the red light of hydrogen (H-alpha). These are dense, somewhat cooler, clouds of material that are suspended above the solar surface by loops of magnetic field.
plages (NASA SP-7, 1965) Clouds of calcium or hydrogen vapor that show up as bright patches on the surface of the photosphere of the sun.
A localized, transient volume of the solar atmosphere in which PLAGEs, SUNSPOTS, FACULAe, FLAREs, etc. may be observed. ACTIVE SURGE REGION (ASR). An ACTIVE REGION that exhibits a group or series of spike-like surges that rise above the limb.
A solar flare is a sudden intense brightening of a small part of the Sun's chromosphere in the vicinity of a plage or facula and often near a sunspot group. The flare develops in a few minutes and may last several hours.
These sites are called active regions, and the surrounding areas, which have smoothly distributed chromospheric emission, are called plages, after the French word for "beach.

coronal condensations in the corona.
Solar flares are also associated with active regions.
Around sunspots, larger field clumps called plage occur (see below), where there are no spicules, but where the chromosphere is generally hotter and denser. In the areas of prominences the magnetic field lines are horizontal and spicules are absent.

bright clouds or "plages" (plah-jes, "beaches" in French) in the chromosphere, seen in the light emitted by glowing hydrogen. Such methods also made possible limited observations of the inner corona, outside times of total solar eclipses.
