Bülletään

X-ray flux remained below B level throughout the period. The Sun is spotless and no flaring is expected.

No Earth-directed CMEs have been observed in coronagraph data.

The proton flux levels were at background values and expected to remain so. High energy electron fluxes are enhanced and expected to rise further due to the ongoing but decaying high speed Solar wind conditions.

Solar wind speed decayed from values around and over 600 km/s to below 500 km/s at the end of the period. The total magnetic field was mostly below 5nT with a variable Bz component. The phi angle remained in the negative sector throughout the period. Solar wind conditions are expected to show a slow and gradual return to nominal conditions over the next days. By late February 10, early February 11, we may see renewed enhancements related to the positive polarity coronal hole in the northern hemisphere.

Geomagnetic conditions were quiet to active (both NOAA Kp and local K Dourbes reached K=4 at midnight). Quiet to unsettled conditions are expected over the next 48 hours.
