Solar eruptions become ‘cannibal’ as a rapid new blob overtakes a slower one

It has been a few busy days for our sun, which has produced three of the eruptions that scientists call coronal mass ejections (CMEs) since Monday (November 1).

CMEs shoot globes of gas and magnetic fields into space, often from sunspots, which are nodes in the sun’s magnetic field. On November 1 and 2, a sunspot designated AR2887 triggered two of these eruptions. So later in the day on Tuesday (November 2), another sunspot called AR2891 also produced a CME.
