However, an active region is about to appear at the South-East limb (probably the return of AR NOAA11052) and may raise slightly the level of activity in the coming days. The solar wind has now slowed down below 400km/s. This should lead to quiet geomagnetic conditions over the rest of the 3-day period. TODAY'S ESTIMATED ISN : 014, BASED ON 05 STATIONS.
