Bulletin

No C-class or even B-class flares were reported during in the past 24 hours. Four sunspot groups reported today have rather simple configurations of the photospheric magnetic field. Unless active regions behind the east limb become flare-productive, a C-class flare is unlikely, although still possible. The Earth is currently inside the trailing part of the ICME driving the shock wave that arrived at the Earth yesterday morning. The interplanetary magnetic field inside the ICME reached 18 nT, but due to its predominantly northward direction the geomagnetic conditions remained on the quiet to unsettled level. The ICME speed is low (up to 450 km/s), so we expect quiet geomagnetic conditions in the coming hours. The solar source of the ICME is not clear. Late on April 2 we expect the arrival of a fast flow from a trans-equatorial coronal hole that reached the solar central meridian late on March 30, possibly resulting in a geomagnetic disturbance up to the minor storm level (K = 5).

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 028, gebaseerd op 15 stations.
