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.

A low latitude positive polarity coronal hole on the Northern hemisphere is transiting the central meridian since this morning. It is expected to influence Solar wind conditions near Earth starting late February 10.

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

Solar wind conditions showed the passage of the high speed stream proper from the Southern polar coronal hole extension. Solar wind speed reached well over 600 km/s (to around 650 km/s around 2UT). Total magnetic field declined from around 10nT to under 5nT over the period. Bz was variable with some peaks don to -8nT. The magnetic field phi angle was in the negative sector throughout the period. Solar wind conditions are expected to remain enhanced initially, while decaying slowly over the next days.

Geomagnetic conditions reached minor storm levels locally (local K Dourbes 5 late yesterday) while NOAA Kp reached active levels (4) at most. Geomagnetic conditions are expected to be quiet to unsettled over the next days with initially some active periods still possible.
