Sun Unleashes Its First X-Class Monster Flare of 2017
Region 2673 just produced a major X2.2 solar flare at approximately 09 10 UTC (Sept 6). This is the first X-Class event to be detected since May 2015. The active region is still in a decent position for Earth directed eruptions. More updates will be provided should a coronal mass ejection (CME) be associated.
