More C flares are likely within the next 48 hours, with a slight chance for an M flare.The solar wind speed ranged between 380 and 470 km/s in the past 24 hours. In the same period, the Interplanetary Magnetic Field was low around 3 to 5 nT. The geomagnetic activity was at quiet levels (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) during the past 24 hours. Quiet geomagnetic conditions (K Dourbes < 4) are expected for September 6 to 8.
