ARLA/CLUSTER: Previsão de fim-de-semana agitado no Sol

[João Gonçalves Costa]

Big Sunspot Notice

After more than a week of quiet, solar activity is picking up with the emergence of two large sunspot groups on the sun's northeastern limb.

The active regions are crackling with C- and M-class solar flares. So far none of the eruptions has been squarely Earth directed, but that could change in the days ahead as solar rotation turns the sunspots to face our planet.
