Bulletin

Although NOAA AR 2209 maintains the beta-gamma-delta configuration of its photospheric magnetic field, it produced only two weak C-class flares during the past 24 hours. The strongest flare was the C1.8 flare peaking at 08:09 UT today. It was not associated with a CME. No other active region produced C-class flares. We expect flaring activity on the C-level to continue in the NOAA AR 2209, with an M-class flare possible but unlikely. The Earth is currently inside a slow (around 450 km/s) solar wind flow with average (5-6 nT) interplanetary magnetic field (IMF) magnitude. Even if the IMF was strongly fluctuating, it was directed predominantly southward during several hours yesterday, resulting in intervals of active geomagnetic conditions (K = 4) reported by Dourbes (one interval) and IZMIRAN (two intervals). Other than that, the geomagnetic conditions are quiet and are expected to remain so, possibly with isolated intervals of active conditions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 066, gebaseerd op 08 stations.
