Faculae are bright regions on the surface of the sun that are often seen near sunspots. Sunspot and faculae are closely related, but the latter is defined as a bright spot or patch on the sun's surface, while the former refers to a dark spot. Other synonyms for faculae include bright points, solar flares, and solar prominences. These terms are all used to describe the bright, active regions of the sun and its surroundings. Faculae are important for studying the sun's activity and can help scientists understand the complex processes that occur on its surface.
