Bulletin

Catania sunspot group 88 (NOAA AR 2192) continues to grow and maintains the beta-gamma-delta configuration of its photospheric magnetic field. The strongest flare it produced during the past 24 hours was the M4.0 flare peaking at 07:48 UT today. This flare was accompanied only with a narrow CME that is not expected to arrive at the Earth. We expect the flaring activity up to X-level from this sunspot group. As the Catania sunspot group 88 is currently situated close to the solar central meridian, a major eruption in this active region may lead to a geoeffective CME and a proton event. A long filament in the northern hemisphere is approaching the solar central meridian. Its possible eruption may lead to an Earth-directed CME. The Earth is currently inside a slow (around 430 km/s) solar wind flow with average (around 6 nT) interplanetary magnetic field (IMF) magnitude. The geomagnetic conditions are quiet and are expected to remain so, with isolated intervals of active conditions (K = 4) possible but unlikely.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 106, gebaseerd op 08 stations.
