Sunspot region 2859 produced a long duration C3.0 solar flare yesterday which launched a coronal mass ejection into space. The plasma cloud has a good chance to impact our planet in a few days time.
The solar flare launched a partial halo coronal mass ejection at a speed of about 500km/s which is moderately slow. The partial halo signature of about 270 degrees gives us confidence that the plasma cloud has a good chance of arriving at Earth. Considering the speed of the plasma cloud, we expect it to arrive at Earth on Monday, 30 August. Active geomagnetic storm conditions (Kp4) are likely with a chance of minor G1 (Kp5) geomagnetic storm conditions.
