Glossary term: Llamarada solar

Also known as Explosión solar, erupción solar, fulguración solar

Description: Es una explosión solar repentina que ocurre cuando las líneas del campo magnético solar se enredan, usualmente localizados encima de una mancha solar, liberando energía en todas las longitudes de onda.

Las llamaradas solares se clasifican según su brillo en rayos X así: llamaradas de clase X o eventos de gran magnitud, clase M o eventos de tamaño medio y clase C que son pequeños y con consecuencias poco notorias en la Tierra.

Otras estrellas también tienen este tipo de explosiones conocidas como llamaradas estelares. Sin embargo, como vemos las estrellas como puntos de luz, solo son notorias las llamaradas con el breve brillo repentino del astro.

The Sun in ultraviolet appears as a circle. The flare is a bright patch in the upper right 3/4 of the way from the center

Solar flare

Caption: This image shows the mid-level solar flare that was observed in March 2022 by the Solar Dynamic Observatory (SDO). The SDO observes the Sun activity, hence it shows the regions on the Sun where there is activity. A solar flare is brief brightening on the sun's surface, this particular flare is an M-class, which means that it is a tenth of the size of the most intense flares, namely the X-flares. Solar flares are barely visible with the naked eye, thus the SDO. The image here, is captured in extreme ultravoilet light that was colourized by red in the SDO, the flare appears in the upper of the solar disk.
