Monster Solar Storm - Strongest in Decades.
Posted 06 September 2017 - 06:47 PM
Early this morning (Sept. 6), the sun released two powerful solar flares — the second was the most powerful in more than a decade.
At 5:10 a.m. EDT (0910 GMT), an X-class solar flare — the most powerful sun-storm category — blasted from a large sunspot on the sun's surface. That flare was the strongest since 2015, at X2.2, but it was dwarfed just 3 hours later, at 8:02 a.m. EDT (1202 GMT), by an X9.3 flare, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC). The last X9 flare occurred in 2006 (coming in at X9.0).
"It was accompanied by radio emissions that suggest there's a potential for a CME," SWPC space scientist Rob Steenburgh told Space.com. "However, we have to wait until we get some coronagraph imagery that would capture that event for a definitive answer."

The smoke was so thick on Monday that I could see sunspot #2673 and #2674 with the naked eye. 2673 is the one that released the big flare.

That time of the cycle to get some fun flares.
