Bulletin

Solar activity was at very low levels. No significant flares have been recorded. A small (beta) region has emerged close to the equator in the east of the solar disk on Jan 24 (as yet unnumbered by NOAA). No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at very low levels.

The solar wind speed ranged between 310 and 360 km/s (ACE). The total magnetic field remained stable with values around 3 nT. Bz varied between -3 and +2 nT. The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector).

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 0 and 1. Quiet conditions are expected on Jan 24-26.

Today's estimated international sunspot number (ISN): 010, based on 09 stations.
