Zonnevlekkengebieden en zonnevlammen

A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. Solar activity has been low. The largest flare was a C8.1 flare (SIDC Flare 3659) peaking on February 19 at 23:45 UTC, which was produced by SIDC Sunspot Group 346 (NOAA Active Regions 3933, 3961, 3990). This sunspot group, together with SIDC Sunspot Group 405 (NOAA Active Region 3996, Beta-Gamma magnetic configuration) and SIDC Sunspot Group 408 (NOAA Active Region 3998, Beta-Delta magnetic configuration) have potential for creating larger flares. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a small chance for X-class flares.

Coronale massa uitstoten

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

Zonnewind

The solar wind speed at Earth has been steady at around 480 km/s in the last 24 hours, with an interplanetary magnetic field currently around 5 nT. Similar conditions, with probably lower solar wind speeds, can be expected in the next 24 hours.

Geomagnetisme

Geomagnetic conditions reached active levels globally and locally (Kp and K_Bel up to 4). Mostly quiet to unsettled conditions can be expected for the next 24 hours.

Proton flux niveaus

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

Elektronenfluxen in geostationaire baan

The greater than 10 MeV GOES 16 and 18 electron flux has been below the threshold in the last 24 hours It is expected to remain below the threshold in the next 24 hours. The 24-hour electron fluence is currently at normal levels and is expected to remain so in the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 134, gebaseerd op 08 stations.
