Solar activity was at very low levels. No significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There was no CME observed in coronagraphic observations associated with the event previously reported at 18:30 UT Jan 19. 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 fluctuated between 270 and 320 km/s (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector). Bz varied between -3 and +8 nT. The total magnetic field oscillated around 3 nT for much of period, then showed an increasing trend from 9 UT Jan 21 reaching a maximum of around 8 nT at 12 UT.

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 0-1. Mostly quiet conditions are expected on Jan 21-23, with possible unsettled periods on Jan 21-22, due to the influence from the patchy negative polarity coronal hole that traversed the central meridian on Jan 16.
