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.
