The flare does not seem to be associated with any CME or SEP event. We expect more flaring activity up to the M-level from this active region, as well as from NOAA AR 1402 (no Catania number yet). The Earth is currently inside a slow (430 km/s) solar wind flow with average (around 4 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions.
