Active region 1890 in the Sun's south eastern hemisphere at S10E30 has potential to trigger severe solar storms. An X-class flare of Intensity X3.3 was released yesterday night with peak intensity at 22:12 UT. A partial halo CME with bulk mass motion to the SE was observed. From November 7 on this region can be a source of earth directed solar storms of major (Kp g.e. 8-) intensity and further flares leading to HF blackouts are likely.
