Bulletin

The solar activity was quiet over the past 24 hours and no flare has been recorded. The sunspot that has emerged yesterday on Jan 06 (NOAA active region 2693) shows already a decay. Quiet flaring conditions are expected for the next 24-hour period with possible but not very likely B to C-class flares from the sunspot.

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 300 and 340 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 high speed streams associated with the coronal hole (which was facing Earth on Jan 05) are not expected to arrive before Jan 08.

The geomagnetic conditions were quiet and it is expected to remain quiet as the Earth is within the slow solar wind speed stream. Disturbance of the geomagnetic conditions are anticipated on Jan 08 due to the arrival of the high speed streams associated with the coronal hole.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 010, basierend auf 09 Stationen.
