Bulletin

Solar flaring activity was low during the last 24 hours, with six C-class flares detected, the brightest being an C3 at 18:42 UTC yesterday. However, all but one of those flares originated from NOAA Active Region (AR) 3088 that is now invisible from Earth. NOAA AR 3092 produced a C1 flare in the previous 24 hours and it is likely to produce some more C-class activity in the next 24 hours.

No Earth directed CMEs 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 last 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 remained affected by the High Speed Stream (HSS) that arrived on 3 Sep. The SW speed ranged between 530 and 630 km/s over the last 24 hours. The total magnetic field (Bt) varied between 3 and 6 nT, while its Bz component ranged between -6 and 6 nT. The interplanetary magnetic field (phi) angle was directed away from the Sun during the last 24 hours. The SW conditions are expected to continue in the same pattern in the next 24 hours.

Geomagnetic conditions reached globally active (Kp 2-4) and locally unsettled (K-Belgium 2-3) levels over the last 24 hours. Unsettled conditions are expected for the next 24 hours with intervals of active conditions.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 095, gebaseerd op 19 stations.
