A region of strong magnetic field without sunspots located at N10E76 has produced a B1.8 flare yesterday evening. The Earth is inside a fast solar wind flow (600 km/s). However, the interplanetary magnetic field is at an average level (4 nT), so the geomagnetic conditions are expected to remain quiet. TODAY'S ESTIMATED ISN : 030, BASED ON 04 STATIONS.
