Sunspot region 12371 kicking out flares

Thursday, June 18 2015 - 12:23 UTC

A coronal mass ejection (CME) is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space.
Coronal Mass Ejections take about  20 to 40 hours to reach the earth. 
CMEs can give rise to ionospheric storms. These can provide a short lived enhancement to ionospheric radio propagation conditions but before long this can result in a black out to radio communications via the ionosphere. 
Lookout for a possible Aurora, If the CME couples strongly to the Earth's magnetic field the Aurora may be visible.

Since then we have had more flares
On June the 20th at 07:09 we had a moderate M1.01 solar flare
On June the 21st at 02:00 we had a moderate M2.03 solar flare
On June the 21st at 02:57 we had a strong M2.69 solar flare
On June the 21st at 10:03 we had a strong M3.87 solar flare
On June the 21st at 18:39 we had a Moderate M1.14 solar flare
All were from from sunspot region 12371

M-flare is double peaked & rises to M2.2! Launching Earth-directed solarstorm now! Likely impact at Earth June 24-25!

Halo CME ‏@halocme Tweeted
Almost circular halo CME (Earth-directed, expected arrival June 23/24). It was associated with M flare. Nice dimming.

SolarHam ‏@SolarHam Tweeted
CME originating from flare site tonight appears to be full halo and Earth directed. More to follow.

A full halo CME is now becoming visible from the M2.0/M2.6 flare. Impact at Earth very likely. More later.
