Bulletin

Despite the emergence of several small sunspot groups (yet unreported by Catania or NOAA), the flaring activity of the Sun is below the C-level. An isolated C-class flare is nevertheless possible, although unlikely. The fast solar wind flow that yesterday produced K = 5 (as reported by Dourbes and IZMIRAN) and K = 4 (as reported by NOAA) is finishing. Currently the solar wind speed around the Earth is close to 450 km/s and the interplanetary magnetic field is around 3-4 nT. We expect quiet geomagnetic conditions in the coming hours. The arrival of the interplanetary shock wave driven by the ICME corresponding to the partial halo CME observed on the Sun on January 23 is still possible, although unlikely.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 049, gebaseerd op 02 stations.
