Surprise: The sun is flaring again
Suddenly, solar flare activity is high. Following months of quiet with negligible flares, new sunspot AR2644 unleashed a series of M-class explosions on April 1st and 2nd.
Each blast produced a shortwave radio blackout over a different part of our planet. The powerful explosions also sent beams of radio energy toward Earth, causing roars of static to issue from the loudspeakers of some shortwave receivers.
Listen to a sample audio file on today's edition of Spaceweather.com, and stay tuned for more flares on April 3rd as the sunspot shows little sign of quieting
