Looks like the new solar cycle is beginning to ramp up. The sun emitted its first X-class flare in more than four years on February 14 at 8:56 p.m. EST.


X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms.


This particular flare comes on the heels of a few M-class and several C-class flares over the past few days. It also has a CME associated with it that is traveling about 900 Km/second and is expected to reach Earth’s orbit on Feb. 16 at about 10 p.m. EST
