The solar wind speed has reached nearly 700km/s and seems to have passed its maximum. The interplanetary magnetic field (IMF) has turned southwards during small intervals. We expect active geomagnetic conditions during the next 24 hours, becoming quiet after. Solar flare activity is remaining at the C-level, most activity originates from groups 90 (NOAA 0424) and 96 (NOAA 0431).
