The sun produced another X-class solar flare today. Even though the responsible sunspot was located behind the edge of the sun, enough radiation reached our planet to cause a strong shortwave radio blackout.
X-CLASS SOLAR FLARE: So long, and thanks for the X-flares. Departing sunspot AR2994 unleashed another X1-class solar flare today, April 30th @ 1347UT, as it exited the Earthside of the sun. NASA’s Solar Dynamics Observatory recorded a spectacular plume of debris flying up and over the sun’s northwestern limb:
