Bulletin

The solar activity has been quiet over the past 24 hours. The visible solar disc remained spotless, and no significant 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.

The solar wind parameters showed a slow return toward the ambient background and slow solar wind speed regime. The wind speed decreased from 530 to 420 km/s. Total interplanetary magnetic field strength was remaining below 6 nT. The southward magnetic component fluctuated between -5 and 5 nT. The solar wind speed is expected to continue its return toward nominal values.

The geomagnetic conditions were quiet with a short unsettled period (K-Dourbes index reached 3 on January 7 at 23:00 and 24:00 UT). The conditions are expected to remain quiet.

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