Solar X-ray flux remained below B level. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux was at nominal levels the past 24 hours and expected to remain so.

Solar wind parameters showed the arrival of the expected high speed stream. Solar wind speed increased since the start of the period from 350km/s to now in the 430-470 km/s range. The total magnetic field reached close to 8nT with a pronounced negative Bz yesterday afternoon (reaching down to -7.3nT). The phi angle was mostly in the negative sector. Solar wind conditions are expected to remain slightly enhanced over the next 24 hours before returning to mostly nominal conditions.

Geomagnetic condition became unsettled yesterday afternoon but were quiet today (NOAA Kp and local K Dourbes 1-3). Quiet to unsettled conditions are expected over the next days with an isolated active period not excluded.
