<p>Our "bad boy" sunspot 1402 is constantly rel flares. At37 UT thctive rn produced the greatest number of flares an X-class flare. It measured X2 being exact. As this active region is rotating inside the limb in the Sun the eruption wasn't Earth directed. But energetic protons faster with the blast are really surrounding the world together with a S1-class radiation storm is going on. S1-class might be the least expensive of 5 (S1 to S5) and contains no biological impact, no satellite methods are affected however, many minor impact on HF radio practical knowledge.
