Bulletin

The solar activity was quiet over the past 24 hours. The visible solar disc is spotless and no C-class flare has been recorded. Quiet flaring conditions are expected for the next 24-hour period.

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.

Over the past 24 hours, the Earth was under the influence of the solar wind associated with the Coronal Hole (which has crossed the central meridian on Dec 28). The solar wind speed has decreased and it is now returning to the slow regime currently fluctuating between 350 and 370 km/s. The interplanetary magnetic field magnitude is below 5 nT, and the Bz competent is ranging between -4 and 4 nT. The solar wind conditions are expected to remain nominal for the next following 24-hour period.

The geomagnetic conditions were quiet and it is expected to remain quiet as the Earth is entering the slow solar wind speed regime.

Today's estimated international sunspot number (ISN): 000, based on 14 stations.
