Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours. The largest flare was a C1.0 flare (SIDC Flare 8337) peaking on August 06 at 19:29 UTC. There are currently 4 numbered regions on the disk. All the regions are simple and either stable or in decay. Solar flaring activity is expected to be low over the next 24 hours.

Coronale massa uitstoten

No new Earth directed Coronal Mass Ejections (CMEs) were detected in the available coronagraph imagery.

Zonnewind

Over the past 24 hours, the solar wind parameters reflected a slow solar wind regime. The magnetic field strength ranged between 1 and 6 nT. The solar wind speed decreased from 310 km/s to around 360 km/s. The solar wind conditions are expected to continue to reflect slow solar wind conditions on August 07, with possible weak enhancements due to any glancing blow from the CMEs from August 03. Further enhancements are possible on August 08 due to a glancing blow CME arrival from August 04 and CIR influence.

Geomagnetisme

Geomagnetic conditions were at quiet levels (NOAA KP and K Bel 1 to 2). Quiet conditions are expected on August 07 with possible active intervals in response to any glancing blow from the CMEs from August 03. Active to minor storm conditions are possible on August 08 due to CME arrival from August 04 and CIR.

Proton flux niveaus

The greater than 10 MeV proton flux was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19, was below the 1000 pfu threshold. The greater than 2 MeV electron flux is expected to be below this threshold over the next 24 hours. The electron fluence was at normal levels and is expected to be at normal levels for the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 055, gebaseerd op 16 stations.
