The solar flaring activity was at low levels over the past 24 hours with only C-class flares mainly from Catania sunspots group 53 (NOAA active region 3038). Currently several sunspots are visible on the disc. The larger flare was a C3.5-class flare from Catania sunspots group 53 (NOAA active region 3038) peaking at 23:36 UTC. We expect mostly C-class flares with a small chance of isolated M-class flares.

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images over the past 24 hours.

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 below 1000 pfu alert threshold and it is expected to remain so during the next 24 hours. The electron fluence was at moderate levels and is expected to return to normal levels in the next 24 hours.

The solar wind parameters in Earth environment were slightly elevated: the wind speed ranged mostly between 400 km/s and 500 km/s with some short periods between 500 km/s and 550 km/s. The interplanetary magnetic field magnitude showed values below 8 nT. The Bz component of the interplanetary magnetic field fluctuated between -6.2 nT and 6.5 nT. Two coronal holes (negative polarity) are currently visible on the disc near the central meridian at high latitudes. The high-speed streams coming from these two coronal holes may influence the solar wind and contribute to its enhancement in the following 2 to 3 days.

The geomagnetic conditions were quiet to unsettle (NOAA Kp and local K-Belgium 1-3). The geomagnetic conditions are expected to continue to be quiet to unsettle conditions.
