NOAA ARs 2472 and 2473 (Catania numbers 4 and 5 respectively) have beta-gamma configuration of their photospheric magnetic field and continue to produce flaring activity. The strongest flare of the past 24 hours was a complex event early today, with the first peak at 02:12 UT (M1.1 in the NOAA AR 2473) and the second peak at 06:16 UT (C5.9 in the NOAA AR 2473 and a nearly simultaneous X-ray flux increase in NOAA AR 2472). The event was associated with a CME first visible in the SOHO/LASCO C2 field of view at 06:12 UT. The full angular width of the CME is not clear yet and will be further evaluated as more LASCO data will be available, although it is unlikely to be a halo CME. We expect C-class flaring in the next 24 hours, with around 50 percent chance for an M-class flare. The Earth is currently inside a solar wind flow with an intermediate speed (around 500 km/s). The interplanetary magnetic field magnitude has been slightly elevated (7-8 nT) in the recent hours, so mostly unsettled with occasionally active geomagnetic conditions were reported. We expect unsettled to possibly active geomagnetic conditions in the coming hours.
