Bulletin

In the past 24 hours, Catania sunspot group 88 (NOAA AR 2192) produced two X-class flares: X1.0 peaking at 17:08 UT yesterday and X2.0 peaking at 10:56 UT today. Neither of the flares seems to be associated with an Earth-directed CME. The area of the Catania sunspot group 88 increases again, and it maintains the beta-gamma-delta configuration of its photospheric magnetic field, so we expect the flaring activity up to X-level from this sunspot group. As the Catania sunspot group 88 is currently situated in the western solar hemisphere, a major eruption in this active region may lead to a proton event. A long filament in the northern hemisphere is continuing its passage across the solar central meridian. Its possible eruption may lead to an Earth-directed CME. The Earth is currently inside a slow (around 370 km/s) solar wind flow with slightly elevated (around 7 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so, with isolated intervals of active (K = 4) geomagnetic conditions possible but not very likely.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 096, gebaseerd op 10 stations.
