Bulletin

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

No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The influence of the coronal hole that transited the central meridian on Jan 8 is weakening. The solar wind speed decreased from around 470 km/s to the current values around 380 km/s. Total interplanetary magnetic field strength was below 6.8 nT. The southward magnetic component remained between -4.1 and 4.1 nT. The influence of the equatorial coronal hole that has reached the central meridian on Jan 9 is expected to re-enhance the solar wind parameters on Jan 13.

The geomagnetic conditions were quiet and are expected to remain quiet until the arrival of the coronal hole influences on the solar wind measurements near Earth on Jan 13. Possible isolated minor storm conditions may be observed, in particular, if the Bz component stays negative for longer periods.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 03 Stationen.
