Bulletin

The strongest flare of the past 24 hours was the C8.1 flare peaking today at 09:47 UT in the Catania sunspot group 80 at the north-east limb (no NOAA AR number yet). SDO/AIA data show the associated coronal dimming indicating the eruption of a CME, although no LASCO data is available to confirm it at the moment of writing. Due to the limb position of the CME source region, we do not expect it to arrive at the Earth and have geomagnetic consequences. We expect flaring activity to remain at the C-level with a small chance for an M-class flare. The Earth is currently inside a slow (around 270 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: 058, gebaseerd op 19 stations.
