Solar Flares & Coronal Mass Ejections: Foundations

Solar flares and coronal mass ejections are major releases of energy from magnetically active regions on the Sun. Monitoring flares and CMEs helps forecast radiation hazards, satellite anomalies, radio disruptions, auroral activity, and geomagnetic storms.

Solar flares and coronal mass ejections are major releases of energy from magnetically active regions on the Sun.

supported

Solar plasma drags and twists magnetic fields as differential rotation and convective motions stress active regions.

supported

Space-based observatories image flares in ultraviolet and X-rays, coronagraphs track CMEs moving away from the Sun, and radio instruments detect accelerated particles.
