Solar X-ray flux remained below background (B) level. With no active regions remaining on disc, solar flaring activity is expected to be very low.

There are no new Earth directed CMEs observed in coronagraph data.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux was slightly enhanced but remained below the 1000 pfu alert threshold and is expected to remain below that threshold over the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Slow Solar wind conditions have been observed with Solar wind speed at around 300 km/s and the interplanetary magnetic field mostly at or below a nominal 5nT, with a variable North-South component. The magnetic field phi angle indicated the interplanetary magnetic field is directed away from the Sun (positive sector). Nominal slow Solar wind conditions are expected over the next 24 hours before we are likely to see, from late January 5, the combined effects of the arrival of the Jan 2 CME together with also a possible general increase in background Solar wind speed due to the high speed streams from the negative polarity Coronal holes that crossed central meridian January 1 and 2.

Geomagnetic conditions were quiet (NOAA Kp 0-1 and local K Dourbes 0-2). Quiet geomagnetic conditions are expected to continue for some 24 hours before an increase to active conditions may be expected associated to the possible CME arrival and general increased Solar wind conditions.
