On September 6, the sun let its presence be felt by unleashing two massive solar flares. The first eruption, classified as an X2.2 flare, the strongest since 2008, occurred at 5:10 a.m. ET. Shortly after, at 8:02 a.m ET, the star spewed out a bigger, and more dramatic, X9.3 flare — the strongest on record since December 2006.
