Bülten

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.

Solar wind parameters showed a slow background solar wind regime (with the wind speeds around 350 km/s) until Feb 11 00:00 UTC. Then the parameters became enhanced due to the expected arrival of the wind streams related to the positive polarity coronal hole, which was facing Earth on February 07. The wind speed increased up to 420-440 km/s, the total interplanetary magnetic fields fluctuated around 6 nT, and the southward magnetic component fluctuated between -6 nT and 5 nT. The solar wind conditions are expected to remain enhanced for the next 2-3 days. 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 later in about 2 days.

With the arrival of the speed streams associated with the coronal hole (positive polarity), periods of unsettled geomagnetic conditions were observed (Kp-NOAA = 3). We expect the geomagnetic conditions to remain quiet to unsettled for the next days.
