Bulletin

Four sunspot groups were reported by Catania today, and non of them was particularly active. The flaring activity at the C-class level is possible, in particular from the newly emerged and fast evolving Catania sunspot group 80. The solar wind speed is about 360 km/s. The interplanetary magnetic field magnitude is slightly elevated reaching the value of about 10 nT. The compression visible in the magnetic field and density might be indication on the arrival of the fast flow associated with the low-latitude coronal hole in the northern hemisphere. The arrival of a CME-driven shock wave associated with the partial-halo CME on February 6 can be expected on early February 10. We expect quiet to possibly unsettled geomagnetic conditions in the next 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 039, gebaseerd op 13 stations.
