FARSIDE EXPLOSIONS CONTINUE: 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):
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.
