Departing sunspot AR2673 erupted again on Sept.10th (1606 UT), producing a major X8-class solar flare which is the 2ND BIGGEST OF SOLAR CYCLE 24. Protons accelerated toward Earth by the explosion are swarming around our planet now, causing a moderately strong solar radiation storm.
A pulse of ultraviolet and X-radiation from the flare ionized the top of Earth's atmosphere, triggering a shortwave radio blackout over the Americas (blackout map #1).However, an even stronger blackout of shortwave radio communications around the poles also occured.
Sunspot AR2673 materialized on Sept. 3rd. Three days later it unleashed the strongest solar flare in more than a decade, an X9.3-class eruption that hurled a CME directly at Earth. Now this memorable sunspot is about to disappear.
Will it still be as potent when it reappears 14 days from now?
