Solar activity was at very low levels. No significant flares have been recorded. 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 increase in the total magnetic field observed from 9 UT Jan 21, as reported in the previous bulletin, continued to develop into an extended feature with a maximum of near 10 nT recorded. The solar wind speed gradually increased from 300 to 400 km/s (ACE). This may signify the arrival of the solar wind associated with the weak negative coronal hole, which passed the central meridian on Jan 16. For the majority of the period the magnetic field oscillated around 7 nT, while Bz varied between -9 and +7 nT. The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector).

Geomagnetic activity was quiet to unsettled, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 1 and 3. Mostly quiet conditions are expected on Jan 22-24, with possible continued unsettled periods on Jan 22 in response to any extended periods of strong negative Bz.
