Since the X3.3 flare yesterday, the NOAA AR 1890 (no Catania number yet) produced only C-class flares, the strongest one being the C8.6 flare peaking at 08:51 UT today. Nevertheless, this active region still keeps the beta-gamma-delta configuration of its photospheric magnetic field. We expect further strong flaring from this region, primarily on the M-level. Another X-class flare is also probable. Given that the NOAA AR 1890 is approaching the solar central meridian, we maintain the warning condition for a proton event. The Earth is currently inside a slow (around 350 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.
