A powerful solar flare that erupted Thursday (Nov. 3) from a huge blemish on the sun's surface has been classified as an X1.9 flare, ranking it in among the most powerful types of storms from our star can unleash.
The flare originated in a humongous sunspot that was sighted earlier this week, which ranks as one of the largest sunspots seen in years. The event began at 4:27 p.m. ET (2027 GMT).
The flare "triggered some disruption to radio communications on Earth beginning about 45 minutes later," NASA officials wrote in a statement. "Scientists are continuing to watch this active region as it could well produce additional solar activity as it passes across the front of the sun."
