Bulletin

Solar flaring activity was low but frequent during the last 24 hours. Catania sunspot group 33 produced most of the activity and is expected to remain active in the next 24 hours. NOAA active region 3098 (Catania sunspot group 30) produced two C1 flares and has undergone flux emergence in the last 24 hours, so it is likely to produce more activity in the coming 24 hours.

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 was above the 1000 pfu alert threshold during the past 24 hours and is expected to remain above this level for the next 24 hours. The 24h electron fluence was at moderate levels in the past 24 hours and is expected to remain at these levels during the next 24 hours.

The Solar Wind (SW) conditions featured a gradual return to a slow wind regime in the last 24 hours. The SW speed gradually dropped from 510 to 400 km/s. The interplanetary magnetic field was mostly directed away from the Sun during the last 24 hours. Its strength fluctuated between 4 and 7 nT, while its north-south component ranged between -6 and 5 nT. The SW conditions are expected to become more typical of the slow wind regime in the next 24 hours.

Geomagnetic conditions reached globally and locally unsettled levels (Kp and K-Belgium 1-3) over the last 24 hours. Unsettled conditions (Kp and K-Belgium 3) are expected to also occur in the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 112, gebaseerd op 15 stations.
