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.
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 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

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.
SDO released one-month videos of comparin the Sun's activity from periods about 2.5 years apart, with remarkable increase in solar activity seen. The video from October, 2010 sets it next to video from May, 2013 in the SDO's 171 Angstrom wavelength
Moderate M2.9 solar flare erupted at 20:56 UTC on June 23, 2013. The event started at 20:48 UTC and ended at 20:59 UTC. The flare originated from Active Region 1778 that just emerged at eastern limb.

A moderate solar flare registered as M2.9, at the peak time, erupted from Region 1777 on June 21, 2013. The event started at 02:30 and peaked at 03:14 UTC. A Type IV Radio Emission was associated with the event. Type IV emissions occur in association with
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
