What Are Solar Faculae, What Causes Solar Faculae, and What Does the Word Faculae Mean In Latin?

Solar faculae are hot areas that appear on the Sun’s surface and are actually clouds of hydrogen just above the photosphere.

Faculae can be easily seen when at the edge, or limb, of the Sun’s disk, but are difficult to distinguish toward the center of the star.

Faculae are produced by concentrations of magnetic field lines.

The word faculae comes from Latin and means “torches.”

As with sunspots, we don’t know very much about solar faculae.
