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.

Solar wind conditions were nominal. Solar wind speed further decreased from around 380 km/s to around 350 km/s. Total magnetic field was around 5 nT with a variable Bz. The magnetic field phi angle was mostly in the negative sector but tended towards the positive sector lately. Nominal solar wind conditions are expected over the next 24 hours with from noon February 5 onwards enhancements due to the fast flow from the extension of the South polar coronal hole.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-2, NOAA Kp 0-3). Mainly quiet to unsettled conditions are expected over the next 24 hours with from noon February 5 onwards, unsettled conditions likely and active periods possible.
