Zonnevlekkengebieden en zonnevlammen

The solar flaring activity was at low level during the last 24 hours with several C-class flares. The strongest flare was GOES C3.1 flare from NOAA AR 3592 which peaked at 17:29 UTC on Mar 03. During the flare, the source region (AR 3592) of the flare had alpha configuration of its photospheric magnetic field. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with few C-class flares, and a low chance for M-class flares.

Coronale massa uitstoten

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations during last 24 hour.

Coronale gaten

A small high latitude northern coronal hole (negative polarity) is crossing the central meridian on Mar 04. No impact from this coronal hole is expected at Earth.

Zonnewind

Over the past 24 hours, the solar wind parameters were disturbed with a strong fluctuations of North-South component (Bz). Bz component ranged between -18 and 17 nT. The fluctuations were due to the arrival of one of the few coronal mass ejections (CME) which was observed on Feb 28. The solar wind speed ranged between 270 km/s to 460 km/s. The interplanetary magnetic field ranged from 4 nT to 19 nT. In the next 24 hours, the solar wind parameters are expected to return to slow solar wind conditions.

Geomagnetisme

Geomagnetic conditions were globally quiet to moderate storm conditions (NOAA Kp 1 to 6-). It was locally quiet to minor storm conditions (K BEL 2 to 5). Global geomagnetic condition was at moderate storm conditions from 18:00 to 21:00 UTC on Mar 03, due to the arrival of one of the few coronal mass ejections (CMEs) that was observed on Feb 28. Quiet to unsettled conditions are expected in the next 24 hours.

Proton flux niveaus

The greater than 10 MeV proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the threshold level in the last 24 hours. It is expected that this parameter to remain below the threshold level in the next 24 hours. The 24h electron fluence continues to be at normal level and is expected to remain normal to moderate level in the coming 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 110, gebaseerd op 22 stations.
