Bulletin

Solar activity has been very low in past 24 h, no flares above the B level. C-class flares remain possible. A partial halo CME (angular width around 120 degrees) erupted on September 4 (first seen at 19:24 UT by LASCO-C2), it originated from a filament eruption. It's slow (210 km/s), faint and directed southwards, but an encounter with the Earth cannot be discarded and may occur on September 9. Geomagnetic conditions are unsettled. The effect from the fast speed stream is fading out, conditions are expected to be quiet to unsettled. Nevertheless, the fast speed stream from a high latitude (northern) coronal hole may arrive to the Earth in 24 to 48 h creating more active periods.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 026, gebaseerd op 16 stations.
