ANOTHER X-CLASS SOLAR FLARE: Departing sunspot AR2673 erupted again on Sept.10th (1606 UT), producing a major X8-class solar flare. A moderately strong solar radiation storm is underway as protons accelerated by the blast swarm around our planet. Shortwave radio blackouts over the Americas and around Earth's poles have also been observed in the aftermath of the explosion. Visit Spaceweather.com for updates and more information.
