It immediately took over the role of the dominant sunspot group and already generated an M2.4 flare. Both sunspot groups are likely to generate C-flares, with a small chance for an M-flare. Geomagnetic conditions have been quiet for the past 24 hours. The solar wind speed is still slightly elevated, but since the IMF is strongly northwards, quiet conditions are expected to continue.
