ARLA/CLUSTER: As surpresas solares de 1 e 2 de Abril de 2017

[João Costa > CT1FBF]

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.

and stay tuned for more flares on April 3rd as the sunspot shows little
sign of quieting
