Space-based observatories recorded another powerful explosion on the farside of the sun today

The blast hurled a bright coronal mass ejection (CME) over the sun’s northeastern limb, shown here in a movie from the Solar and Heliospheric Observatory (SOHO)

NASA’s STEREO-A spacecraft, which has a partial view of the sun’s farside, pinpointed the explosion: The source appears to be old sunspot AR2665. The huge active region crossed the Earthside of the sun in early July, sparking moderately strong geomagnetic storms when it faced our planet. Apparently, it is still active, producing at least three significant CMEs since it began its farside transit more than 10 days ago.

AR2665 will spin back around to face Earth in early August. If the sunspot continues to explode, it could bring a new round of geomagnetic storms and auroras to our planet. Stay tuned. Free: Solar Flare Alerts
