Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was high over the past 24 hours, with 9 M-class flares identified. The largest flare was a M3.79 flare (SIDC Flare 2488) peaking on November 04 at 01:40 UTC, which was produced by SIDC Sunspot Group 305 (NOAA Active Region 3883), which produced most of the flaring activity in the last 24 hours. This region together with SIDC Sunspot Group 217 (NOAA Active Region 3878) are the most magnetically complex regions on disk, classified as magnetic type beta- gamma-delta. A total of 13 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 306 (NOAA Active Region 3885) currently located at S10W43 has emerged unto the solar disk. SIDC Sunspot Group 283 (NOAA Active Region 3886) currently located at S06E65 has rotated on the visible disk. Four regions are expected to rotate over the west limb. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected, M-class flares very likely and a small chance for an X-class flare.

Coronale massa uitstoten

A Coronal Mass Ejections (CMEs) have been detected in LASCO/C2 coronagraph imagery, lifting off around 00:36 UTC on November 04 from the north-east quadrant. Further analysis of the event is ongoing.

Zonnewind

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) remained slightly elevated. The interplanetary magnetic field, B, reached a maximum value of 9 nT with a minimum Bz of -6 nT. The solar wind velocity ranged between 402 and 470 km/s. The phi-angle was mainly in the positive sector (directed away from the Sun), with periods in the negative sector. The solar wind conditions are expected to gradually return to the slow solar wind regime over the next 24 hours.

Geomagnetisme

The geomagnetic conditions over the past 24 hours were locally and globally quite to active (Kp 1-4 and K BEL 1-4 ). Quiet to active geomagnetic conditions are expected for the next 24 hours.

Proton flux niveaus

Over the past 24 hours the greater than 10 MeV GOES proton flux continued to decrease towards background levels. The greater than 10 MeV GOES proton flux is expected to decrease to nominal levels over the 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux measured by GOES 16 was below the 1000 pfu threshold and is expected to remain so in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 194, gebaseerd op 11 stations.
