X-Flare causes Radio blackout on 25th April

[Carole]

X-FLARE: On April 25th, an active region near the sun's western limb erupted, producing an impulsive X-class solar flare.  A pulse of extreme UV radiation from the flare ionized Earth's upper atmosphere and caused a shortwave radio blackout on the dayside of Earth.   However, a CME hurled into space by the explosion will miss our planet.  Check http://spaceweather.com for updates.
