On April 3, another powerful flare of class M 5.8 occurred on the Sun, which was accompanied by a massive ejection of the solar mass.
The source of the outbreak is the outgoing spot of AR 2644, while the huge sunspot of AR 2645, directed to the Earth, continues to grow, but so far has not shown much activity.
Earlier on 01-02 April several class flares from M 2.1 to M 5.7 occurred on the Sun, but today’s outbreak is still the most powerful in 2017.
