Solar flaring activity was at low levels, with four C-class flares detected over the last 24 hours. Both NOAA Active Regions (AR) 3126 and 3130 (Catania groups 68 and 72, both with magnetic type Beta) experienced sudden growth, with NOAA AR 3126 producing the brightest flare (a C4) and NOAA 3130 producing the remaining three (two C1 and one C2). More C-class flare activity is expected in the next 24 hours as both NOAA AR 3126 and 3130 remain magnetically complex.

No Earth-directed Coronal Mass Ejections were observed in the last 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 remained below the 1000 pfu alert threshold and is expected to remain below this threshold during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

The Solar Wind (SW) conditions remained affected by the arrival of a High Speed Stream (HSS) that took place yesterday. The SW speed fluctuated between 470 and 580 km/s in the last 24 hours. The total magnetic field (Bt) dropped from a pick of 13 nT to just 2 nT, while its north-south component (Bz) varied between -8 and 10 nT in the last 24 hours. The interplanetary magnetic field (phi) angle was negative (directed towards the Sun) during the last 24 hours. The SW conditions are expected to remain under the influence of the HSS for the next 24 hours.

Geomagnetic conditions reached globally and locally active levels (NOAA Kp 2-4 and K Belgium 1-4) over the last 24 hours. In the next 24 hours the conditions are expected to most likely be unsettled (Kp and K Bel up to 3) or active (Kp and K Bel 4) at most.
