A high-speed solar wind stream from a geoeffective coronal hole is buffeting Earth's magnetic field and causing geomagnetic storms around the poles. The Bz component of the interplanetary magnetic field (IMF) is rotating between north and south pointing
Active Region 1817 erupted with moderate solar flare peaking as M1.5 at 10:41 UTC on August 12, 2013. AR 1817 has Beta magnetic configuration and is located in Sun's southern hemisphere. It is still growing and rotating into geoeffective position. Any new
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.
STEREO Ahead and STEREO Behind COR2 images show the prominence flaring on July 22, 2013
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,
