: a tremendous outburst of energy from the corona of the sun that can cause disruptions in the earth's geomagnetic field
As they had for the January eruption, the researchers relied on an armada of spacecraft to track the disturbance, known as a coronal mass ejection because it originates in the sun's outer atmosphere, or corona.—
