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.

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

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.
