A solar flare just knocked out radio transmissions across the US – and it won’t be the last

The Sun has been very active lately, sending out scorching flares and frying communication systems back on Earth. The latest one was recorded on Monday when an X-class solar flare disrupted radio and navigation signals across North America.

‘X-class’ solar flares are the largest, most disruptive of flares and this one, classified as an X1.5, likely disrupted high-frequency radio communications on the sunlit side of Earth. According to the Met Office, the flare burst out of the largest and most active sunspot group currently visible on the Sun’s disk.

This was the 20th X flare of the current 11-year solar cycle, which is due to reach its peak next year. Monday’s flare followed another weaker X-class solar flare just two days earlier. The activity was detected by Nasa’s Solar Dynamics Observatory (SDO) which captured an image of the action.

Solar flares are powerful bursts of energy that can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. The Sun has seen a flurry of activity on its surface this year, with Nasa astronomers spotting multiple ‘coronal holes’ on our star.
