Halo CME -- 18 February 2000
 |
| The ESA/NASA Solar and Heliospheric
Observatory recorded this image of a coronal mass
ejection (CME). This is called a `halo', since the plasma bubble
being ejected is directed towards the Earth. As it moves away from
the sun, it appears as an expanding annulus, earning it the
name.
The blue disk blocks out the Sun's bright light; the white circle near the center shows the true size of the Sun. |
