The sunspot, called AR2975, has been shooting out flares of electrically charged particles from the sun’s plasma soup since Monday (March 28). Sunspots are areas on the sun’s surface where powerful magnetic fields, created by the flow of electrical charges, knot into kinks before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares, or explosive jets of solar material called coronal mass ejections (CMEs).

Cannibal coronal mass ejections happen when fast-moving solar eruptions overtake earlier eruptions in the same region of space, sweeping up charged particles to form a giant, combined wavefront that triggers a powerful geomagnetic storm.
