Only active region NOAA11598 keeps the potential for an M flare, and possibly an X flare. Indeed, it is still growing, mainly in its following part, and it keeps its beta-delta magnetic configuration. As it is now approaching the solar central meridian, any CME spawned by this region will be Earth-directed in the coming 6 to 7 days. With the current slow and and very steady solar wind, we expect quiet geomagnetic conditions for the next 3 days. TODAY'S ESTIMATED ISN : 063, BASED ON 14 STATIONS.
