From spaceweather.com:
SOLAR FLARE AND RADIO BLACKOUT: Unstable sunspot AR3288 erupted today, May 1st at 1309 UT, producing a brief but intense M7-class solar flare. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash:
Radiation from the flare ionized the top of Earth's atmosphere, disrupting the normal propagation of radio transmissions on the planet below. Mariners and ham radio operators around the Atlantic Ocean may have noticed loss of signal below 20 MHz for as much as 30 minutes after the explosion.
This flare was probably too brief to lift a coronal mass ejection (CME) out of the sun's atmosphere. Stay tuned for confirmation from SOHO coronagraphs in the hours ahead. Solar flare alerts: SMS Text.
