Bulletin

Three M-class flares were detected in the past 24 hours, all of them produced by the Catania sunspot group 88 (NOAA AR 2192). The strongest flare was the M8.7 flare peaking at 01:59 UT. Based on the still incomplete SOHO/LASCO data and the absence of conspicuous eruptive signatures in the SDO/AIA data, we conclude that there was no CME associated with this flare. We expect flaring activity mostly on the M-level in this group, with a good chance for an X-class flare. As the Catania sunspot group 88 approaches the solar central meridian, a major eruption in this active region may lead to a geoeffective CME and a proton event. The Earth is currently inside a slow (around 460 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 095, gebaseerd op 10 stations.
