The main driver of solar activity is likely to be NOAA AR 1654, which has produced several C flares in the past 24 hours, and a M1.2 flare, today, at 0911 UT (peak time). A metric type II burst was observed, and a CME was probably associated to it. At the time this message is prepared, coronagraphic observations do not allow to see if a CME has indeed occurred. Active conditions (M flare likely) are expected for the next 48 hours from this region, with a risk of an X class flare. Geomagnetic conditions might evolve quickly from quiet to active levels in the coming days if CMEs related to NOAA AR 1654 flares occur; which justifies issuing a warning condition.
