Solar activity was at very low levels. No significant flares have been recorded. NOAA Active Region 2757 (N03E09) showed some sunspot growth and continued flux emergence and produced A-flaring activity over the period (GOES-16). Another active region with possible spot development has also rotated over the eastern limb (S30E70). A very slow and narrow Coronal Mass Ejection (CME) that may be Earth directed was observed by STEREO-A at 17:54 Jan 25, possibly associated with an extended A-flare at 15:00 from AR2757. There are currently no LASCO observations for this time, however, due to the extremely slow speed it is not expected to have a significant geomagnetic impact. Further analysis will be carried out as the data becomes available. 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 was at background levels, ranging between 260 and 350 km/s (ACE). The total magnetic field fluctuated between 0 and 7 nT. Bz. The interplanetary magnetic field (phi angle) was predominantly directed away from the Sun (positive sector).

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 0 and 2. Quiet conditions are expected on Jan 26-28.
