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. Our planet's magnetosphere might receive a glancing blow on October 2 – 3 when polar geomagnetic storms and auroras are possible. 

Low energy proton levels streaming past Earth are still on the rise. S1 (Minor) solar radiation storm conditions are expected on September 30 and October 1 due to particle enhancement associated with the CME. Minor impacts on polar HF (high frequency) radio propagation resulting in fades at lower frequencies are expected.

CME is visible in the STEREO Behind COR2 and SOHO Lasco C3 imagery below:

NOAA SWPC forecasters estimated 5% chance for an M-class flare, and 01% chance for an X-class solar flare today.

We are currently experiencing weakest solar maximum in 100 years.
