Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was low over the past 24 hours, with several C-class flares recorded. The largest flare was a C3.0 flare (SIDC Flare 6582) peaking on January 05 at 09:20 UTC, associated with SIDC Sunspot Group 722 (NOAA Active Region 4334; magnetic type alpha). There are currently seven numbered active regions on the visible solar disk. SIDC Sunspot Group 745 (NOAA Active Region 4325, magnetic type beta-gamma) remains the largest and most complex active region, but produced only low-level C-class flaring. Low flaring activity was also produced by SIDC Sunspot Group 744 (NOAA Active Region 4324; magnetic type alpha) and by SIDC Sunspot Group 754 (NOAA Active Region 4336; magnetic type beta). The remaining active regions are relatively simple (magnetic type alpha or beta) and did not produce any significant flaring activity. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares expected and a M-class flares possible.

Krooniaine massiline väljavool

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images over the past 24 hours.

Päikesetuul

A shock was registered in the solar wind data around 20:40 UTC on January 01, likely associated with a CME that lifted off the solar surface at around 18:00 on January 01 (SIDC CME 618). The interplanetary magnetic field quickly jumped from 440 to 470 km/s. The southward component of the interplanetary magnetic field reached minimum values -10 nT. Solar wind conditions are expected to remain slightly elevated on January 05 due to the ICME passage, before gradually returning to slow solar wind conditions.

Geomagnetism

Geomagnetic conditions reached active levels globally (NOAA Kp = 4, 4+) between 03:00 and 09:00 UTC on January 5 due to the ICME arrival. Locally over Belgium, quiet to unsettled conditions were observed (K-Bel = 1 to 3). Mostly quiet to unsettled geomagnetic conditions are expected over the next 24 hours, with a chance of isolated active periods.

Prootoni voo tasemed

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, exceeded the 1000 pfu threshold. The greater than 2 MeV electron flux may exceed the 1000 pfu threshold over the next 24 hours. The electron fluence was at moderate levels and is expected to be at normal to moderate levels for the next 24 hours.
