Only small B flares are expected, with a low probability of an isolated C flare. The solar wind speed has further declined to 450km/s, with a weak interplanetary magnetic field. Consequently, all ground magnetographs are now recording quiet conditions. The geomagnetic field should remain quiet to unsettled at least over the next 2 or 3 days.
