Space Weather News for April 25, 2014 http://spaceweather.com
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.

Peter,
That can happen when the illumination is poor, but also if there is someone using too much power. They can bounce the entire transponder, resulting in very choppy, distorted audio.
