Zonnevlekkengebieden en zonnevlammen

There are six active regions visible on the disk. Solar activity was driven by the active regions rotating out of view over the west limb. There is a new region that rotated into view, NOAA AR 3488 (alpha magnetic field configuration). The strongest flare was an M1.1 from NOAA AR 3485 (beta magnetic field configuration) peaking at 23:05 UTC on 14 November. More M-class flares can occur in the next 24 hours.

Coronale massa uitstoten

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

Zonnewind

In the last 24 hours, the solar wind conditions at the Earth have returned to a slow wind regime. The interplanetary magnetic field is around 7nT and the solar wind speed around 450 km/s. Similar conditions can be expected in the next 24 hours.

Geomagnetisme

During the last 24 hours the geomagnetic conditions were quiet to unsettled globally (NOAA KP 3) and reached active levels locally (K_Bel 4). Mostly quiet to unsettled conditions are expected for the next 24 hours.

Proton flux niveaus

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels. Due to the proximity to the west limb of an active region producing M-class flares, a warning condition for proton events is active for the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux was below the 1000 pfu threshold, as measured by GOES 16. It is expected to remain so in the next 24 hours. The 24 hour electron fluence was at normal levels, it is expected to stay at those levels for the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 036, gebaseerd op 15 stations.
