The sun has fired another blast directly at Earth. A class M8.4 solar X-ray flare just was just sent hurling in our direction at 12:44 PM (EST) today from sunspot (AR1429) again . This is a major flare that is just a couple of points short of an X-Class flare and it is directly facing Earth so we will feel it with full force. Our magnetosphere is already stressed from the recent barrage and this can’t make things any better. The chance of a strong geomagnetic storm is probable. This post will be updated as more details are determined. Sometime during the morning of March 12, a strong (K7 or higher) geomagnetic storm will arrive in the form of a magnetic cloud resulting from the full halo CME generated on March 9.
