Weak CME impact and filament channel eruption on the Sun

An interplanetary shock wave hit our planet's geomagnetic field on June 27, 2013 at approximately 14:20 UTC. Geomagnetic Sudden Impulse was registered at 14:40 UTC. The impact was relatively weak and has not caused a geomagnetic storming so far.

Farside eruption generated bright Coronal Mass Ejection (CME)

STEREO Ahead COR 2 recorded farside eruption that produced bright Coronal Mass Ejection (CME). A new active region transiting the farside will rotate into Earthside later this week.This CME was directed away from Earth and pose no danger to our
