Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was very low over the past 24 hours. The X-ray flux was below C level. Only 1 numbered sunspot group was identified on the disk over the past 24 hours: SIDC Sunspot Group 946 (NOAA Active Region 4528) currently located at S11W83, with an Alpha magnetic configuration and was stable over the past 24 hours. Solar flaring activity is expected to be very low over the next 24 hours, with a small chance for C-class flares.

Coronale massa uitstoten

No Earth directed CMEs were detected in the last 24 hours.

Zonnewind

The solar wind has been gradually returning to a slow solar wind configuration in the last 24 hours. The solar wind speed is at present close to 410 km/s and the interplanetary magnetic field intensity is around 4 nT. Similar conditions can be expected for the next 24 hours.

Geomagnetisme

Geomagnetic conditions have been quiet to unsettled both locally and at planetary levels (Kp and K_Bel up to 3). Similar conditions can be expected for the next 24 hours.

Proton flux niveaus

The greater than 10 MeV proton flux on GOES-18 is at background levels.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19, remained below the 1000 pfu alert threshold over the past 24 hours and is expected to remain so over the next 24 hours.The 24-hour electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 006, gebaseerd op 17 stations.
