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 for 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 continued to return towards an ambient background and slow solar wind speed regime. The wind speed decreased from around 450 km/s to around 350 km/s. Total interplanetary magnetic fields remained below 5 nT, the southward component ranged between -3.5 nT and 3.0 nT. Solar wind conditions are expected to further return to a nominal regime over the next few hours. Some enhancements are expected later in the day on February 10 and early February 11, with the arrival of fast solar wind streams in relation to a positive polarity coronal hole in the northern solar hemisphere, which was facing Earth on February 07.

Quiet geomagnetic conditions were observed with Kp-index (NOAA) and K-Dourbes index ranging between 0 and 2. Unsettle to active conditions is likely later on February 10 and February 11, when the solar wind streams from the positive polarity coronal hole is reaching Earth.
