The sun unleashed a powerful solar flare late Monday (Oct. 22), releasing waves of radiation into space that have already caused a short radio blackout on Earth.

The flare erupted from the sunspot AR 11598 (short for Active Region 11598), and reached peak brightness at 11:22 p.m. EDT (0322 GMT this morning, Oct. 23), according to scientists working on NASA's Solar Dynamics Observatory (SDO), a space telescope that constantly monitors the sun with high-definition cameras. It ranked as an X1.8 solar flare, one of the strongest types of solar flares, according to the U.S. Space Weather Prediction Center (SWPC) run by NOAA and the National Weather Service.

The same sunspot produced three strong flares before this one in just the two days since it became visible from Earth's perspective. "This means more flares are probably in the offing, and they will become increasingly Earth-directed as the sunspot turns toward our planet in the days ahead," astronomer Tony Phillips wrote on Spaceweather.com, a website that tracks skywatching and space weather events.
