The solar wind is stable and very smooth, at a low speed (320 km/s) and with a weak magnetic field (3 nT). We thus expect quiet geomagnetic conditions and we extend our all-quiet forecast for the next 48hours. Thereafter, a faster wind may reach the Earth due to a small equatorial coronal hole now at central meridian. TODAY'S ESTIMATED ISN : 007, BASED ON 03 STATIONS.
