Un fenómeno pocas veces visible en el que nuestro astro rey expulsa una considerable cantidad de materia solar “coronal mass ejection (CME)”. Estos fenómenos que tienen asociados cambios importantes en los campos magnéticos pueden ser de diferente índole.
En el video se observa uno de ellos en el que la masa expulsada retorna por efecto gravitacional en forma de “lluvia”. Las proporciones del fenómeno se ilustran al comparar la llamarada con el tamaño del planeta tierra.
On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain. Hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly falls back to the solar surface.
