Zonnevlekkengebieden en zonnevlammen

There are ten visible active regions on the solar disk. Mostly C-class flaring has been observed in the last 24 hours, from NOAA ARs 3319 and 3323. Nevertheless, there was one M-class flare from NOAA AR 3324: M1.5 peaking at 02:41 UTC. NOAA AR 3315 which caused many flares this week is now rotating out of view over the west limb. More M-class flares can be expected and X-class flares are possible.

Coronale massa uitstoten

No Earth-directed coronal mass ejections (CMEs) were detected in the past 24 hours.

Coronale gaten

There are two positive polarity coronal holes, a small close to the equator and another one in the south. The solar wind from these coronal holes may still affect the Earth today.

Zonnewind

In the last 24 hours we saw the passage of a mild high speed stream, speeds up to 500 km/s and interplanetary magnetic field up to 9 nT. Since there are two (small) coronal holes visible, we may still some increases in solar wind speed today. Otherwise, over the next 24 hours we expect a return to slow solar wind.

Geomagnetisme

The geomagnetic conditions over the past 24 hours reached active levels locally (K_Belgium up to 4) and moderate at planetary scale (Kp up to 3). Moderate to active periods can be 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 and is expected to remain so in the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux was below the 1000 pfu threshold over the past 24 hours and is expected to remain so in the next 24 hours. The 24h 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: 133, gebaseerd op 19 stations.
