Zonnevlekkengebieden en zonnevlammen

There are six active regions visible on the disk. Flaring activity has been low, with only minor C-class flaring in the last 24 hours. The strongest one was a C2.9 flare from NOAA AR 3477 (beta magnetic field configuration), peaking at 20:50 UTC on 13 November. NOAA AR 3483 has a beta-gamma magnetic field configuration while the other regions have simpler beta magnetic field configuration. Most of these active regions are rotation out of view over the west limb. More C-class flares are expected.

Coronale massa uitstoten

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

Zonnewind

In the last 24 hours, the Earth was under the influence of an ICME corresponding probably to an early arrival of the CME from 10 November. The ICME arrived around 16:20 UTC on 13 November with an interplanetary magnetic field reaching 15 nT (with positive Bz) and solar wind speed around 450 km/s. Similar disturbed conditions can be expected for the next 24 hours.

Geomagnetisme

During the last 24 hours the geomagnetic conditions were quiet to unsettled (NOAA KP 3, K_Bel 3). Since Bz was positive within the ICME so far, its geomagnetic impact was minor. Similar conditions can be expected in the next 24 hours, with possible active and minor storm periods if Bz turns negative.

Proton flux niveaus

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over 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 moderate levels, it is expected to stay at those levels for the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 060, gebaseerd op 10 stations.
