The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless and the X-ray flux is below B-level. The solar activity is expected to remain at low levels over the next 24 hours.

No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

The influence of the high-speed stream coming from the positive polarity coronal hole has dropped on February 11 around 19:30 UTC when the phi angle switched to the negative sector. The solar wind parameters remained, however, slightly enhanced. The wind speed first decreased up to 350 km/s to then re-increase up to 420 km/s, the total interplanetary magnetic fields was below 6 nT, and the southward magnetic component fluctuated between -4.5 nT and 5.0 nT. The solar wind conditions are expected to remain slightly enhanced for the next 24-hour period. Solar wind coming from the equatorial coronal hole (negative polarity) that reached the central meridian on February 9, may then contribute to the solar wind enhancement in about 1-2 days.

The geomagnetic conditions were quiet with few short periods of unsettle condition observed in Dourbes station (K-Dourbes = 3). We expect the geomagnetic conditions to remain mostly quiet with some short sporadic periods of unsettled condition for the next days.
