The Sun blew out a powerful coronal mass ejection (CME) from just around the edge of the Sun (Oct. 14, 2014). The particle cloud expanded around all the Sun in a rough circle, hence the name halo CME. This event was also associated with a fairly strong flare. The active region that was the source of these events is just rotating into view. Then, we can better observe its size and structure. The bright object to the right and just above the Sun is Venus now on the far side of the Sun. Credit: NASA/ESA/SOHO
