Southern hemisphere of the Sun is showing an uptick in activity. Beta classified Region 1817 produced an C8.4 solar flare peaking at 21:55 UTC on Sunday, August 11, 2013. This was the largest Earth facing X-ray event since July 8.

A spectacular filament eruption was observed yesterday August 6, 2013 at 02:04 UTC. A strong Coronal Mass Ejection (CME) has been seen following this energetic impulsive eruption and it does seem to have an earth-bound component which should impact the
As it does approximately every 11 years on a solar cycle, the Sun's magnetic field is now reversing. Measurements have confirmed that we are about 3 – 4 months away from complete magnetic field reversal when Sun's inner magnetic dynamo will re-organize itself.
During last 24 hours solar wind stream buffeted Earth's magnetic field causing geomagnetic storms around the poles. Geomagnetic conditions were short lived reaching G1 – Minor geomagnetic storm levels (Kp=5). At those levels weak power
This movie provides an overview of nine great solar prominences that were visible in July 2013.

A large prominence lifted off the northwest limb on July 21, 2013 and generated a Coronal Mass Ejection (CME), directed to the north and away from Earth.

A minor geomagnetic storm is currently in progress due to slow-moving CME that erupted on July 9, 2013 and swept past Earth on July 13, 2013. The Bz component of the interplanetary magnetic field (IMF) tipped sharply south late on July 14,

We saw increased geomagnetic activity for past two days as Kp index reached K=5, G1 geomagnetic storming level, on July 10. A minor CME hit Earth's magnetic field on July 9, 2013 at approximately 20:30 UTC and peaked during the early hours of
A moderate solar flare reaching M1.5, at its peak time, erupted on July 3, 2013. The event started at 07:00, peaked at 07:08 and ended at 07:18 UTC. The source of the event was probably Beta classified Region 1785 located on the Sun's eastern limb or the
