Large prominence eruption off the northeast limb

A large prominence located off the northeast limb erupted early on Tuesday, October 8, 2013. A non-Earth directed Coronal Mass Ejection (CME) was associated with the event.There are currently 6 numbered sunspot regions on the disk.1855 - Beta1856 - Beta1857 - Alpha1860

Long duration C1 solar flare erupted with Earth directed CME

A long duration C1 solar flare erupted on October 6, 2013 at 14:24 UTC. Coronal Mass Ejection associated with this event is Earth directed. Plasma cloud is forecast to sweep past our planet sometime on October 9 resulting in minor increase in geomagnetic

Large magnetic filament erupted during the late hours of September 29

A large magnetic filament erupted on Sun's northern hemisphere during the late hours (UTC) of September 29, 2013. The explosion hurled a magnificent Coronal Mass Ejection (CME) into space and it does look like it has an Earth-directed component.

Prominence eruption and long duration solar flare with Full-Halo CME

A long duration C-Class solar flare reaching C8.3 erupted on August 30, 2013 peaking at 02:46 UTC. The event started at 02:04 UTC and ended at 04:06 UTC. Associated was Type II and Type IV radio emissions. Type IV emissions occur in association with major

Sungrazing comet and farside full-halo CME

An icy comet with estimated size of few tens of meters plunged into the Sun on August 19/20, 2013 but just before it dissipated, a far-side region on the Sun expelled a magnificent full-halo CME. Today's comet belonged to Kreutz Sungrazer family which

Large filament eruption to deliver a glancing blow early Friday

A large solar filament located in the southern hemisphere lifted off the Sun at about 8:50 UTC on August 20, 2013. A bright Coronal Mass Ejection (CME) was produced as the result. Though the majority of Sun's material is directed south current

Impulsive solar flare measuring M3.3 erupted from Region 1818 - CME produced

An impulsive solar flare reaching M3.3 erupted on August 17, 2013. The event peaked at 18:24 UTC from Active Region 1818. AR 1818 is classified with Beta-Gamma-Delta magnetic configuration and is capable of producing even stronger eruptions.  At 18:49

Moderate solar flare reaching M1.5 erupted from Region 1817

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

An uptick in solar activity on southern hemisphere of the Sun

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. NOAA SWPC

Spectacular filament eruption & Earth directed CME - August 6, 2013

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

Magnetic pole reversal of the Sun 3 - 4 months away

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.

Large solar prominence on the northwest limb

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

Massive sunspot complex on southern hemisphere indicates a possible double peaked solar maximum

A massive array of sunspots AR1785 - 1787 has rotated over the Sun's southeastern limb and will position itself directly facing Earth in the coming days. This sunspot complex is one of the largest in Solar Cycle 24 and is located in southern
