Bulletin

The solar activity was quiet over the past 24 hours and no flare has been recorded. Quiet flaring conditions are expected for the next 24-hour period with possible but not very likely B to C-class flares from the small sunspot turning around the West limb.

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 solar wind conditions were within the slow wind speed stream over the past 24 hours. The solar wind speed was ranging between 280 and 300 km/s. The interplanetary magnetic field magnitude was below 5 nT, and the Bz component was ranging from -4 to 4 nT. Solar wind enhancements and wind speed streams associated with the coronal hole (which was facing Earth on Jan 05) are expected to arrive tomorrow on Jan 08.

The geomagnetic conditions were quiet as the Earth was within the slow solar wind speed stream. Some disturbances of the geomagnetic conditions are anticipated due to the arrival of the wind speed streams associated with the coronal hole. And moderate to active geomagnetic conditions can be expected tomorrow on Jan 08.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 12 Stationen.
