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 peaking above the event threshold. They are expected to remain elevated for the next few days in the wake of the decaying high speed Solar wind conditions.

Solar wind conditions continued to decline. Solar wind speed dropped from around 500 km/s to around 430 km/s. Total magnetic field was around 5nT with the magnetic field phi angle continuing to be in the negative sector. Solar wind conditions are expected to further return to a nominal regime over the next 24 hours with later a renewed enhancement expected late February 10, early February 11, in relation to a positive polarity coronal hole in the northern Solar hemisphere.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-2 and NOAA Kp 1-3).
