NOAA AR 1785 and 1787 seem to have reached their peak size but M-class flares remain likely in the next 24h. The z-component of the interplanetary magnetic field is at -10 nT since yesterday evening. No shock was seen in the solar wind speed, which remains slow at 350 km/s. Nevertheless active geomagnetic conditions can be expected in the coming hours.
