3. X2-class solar flare causes radio blackout


Emerging sunspot AR2339 unleashed an intense X2-class solar flare on May 5th at approximately 22:11 UT.

Radiation from the flare caused strong radio blackouts on the Pacific side of Earth, interfering with communications at frequencies below ~20 MHz.

The blast also hurled a CME into space, but not toward Earth.

This event could herald a sustained period of high solar activity, as AR2339 appears to be large and explosive.
