Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours, with only C1 or fainter flares identified. SIDC Sunspot Group (SG) 938 (NOAA Active Region 4505, Beta magnetic configuration) produced all the notable flaring activity. More low C-class flaring activity, associated with SIDC SG 938, is expected to register in the next 24 hours.

Coronale massa uitstoten

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Zonnewind

The Solar Wind (SW) conditions of the past 24 hours feature a slow SW regime. The SW speed ranged between 380 and 470 km/s, the interplanetary magnetic field (B) was between 4 and 7 nT, and its North- South component (Bz) varied from -4 to 6 nT. The SW conditions are expected to remain at the current levels in the next 24 hours.

Geomagnetisme

The geomagnetic conditions of the past 24 hours were at quiet levels both globally and locally (NOAA Kp 1 to 2 and K BEL 1 to 2). In the next 24 hours it is likely that they will continue at quiet levels.

Proton flux niveaus

The greater than 10 MeV proton flux, as measured by the GOES-19, was at nominal levels over the past 24 hours and is expected to remain so in the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux as, measured by GOES 19, was below the 1000 pfu alert threshold for past 24 hours. It is expected to remain at the same levels in the next 24 hours. The electron fluence was at normal levels in the past 24 hours and it is expected to remain at the same levels in the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 042, gebaseerd op 20 stations.
