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 reached a maximum of 491 km/s on Jan 01 at around 15:37, it has then globally decreased and reached the current value of about 445 km/s. The interplanetary magnetic field magnitude is below 6 nT, and the Bz competent is ranging between -5 and 5 nT. The solar wind speed is expected to decrease further and return to nominal regime by tomorrow.
The geomagnetic conditions were unsettled to quiet. It is expected to be mainly quiet with the weakening of the solar wind stream associated with the coronal hole and return to nominal conditions by tomorrow.
Today's estimated international sunspot number (ISN): 000, based on 11 stations.
