Biggest solar flare in years temporarily disrupts radio signals on Earth

A NASA telescope has captured the biggest solar flare in years, which temporarily knocked out radio communication on Earth.

The sun spit out the huge flare along with a massive radio burst on Thursday, causing two hours of radio interference in parts of the U.S. and other sunlit parts of the world. Scientists at the National Oceanic and Atmospheric Administration said it was the biggest flare since 2017, and the radio burst was extensive, affecting even the higher frequencies.

The combination resulted in one of the largest solar radio events ever recorded, Shawn Dahl of NOAA’s Space Weather Prediction Center said Friday.
