Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C4.9 flare (SIDC Flare 6485) peaking on December 24 at 10:21 UTC, which was produced by SIDC Sunspot Group 735 (NOAA Active Region 4317). A total of 8 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 735 (NOAA Active Region 4317) is the most complex region with its Beta-Gamma magnetic configuration. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Koronalny wyrzut masy

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

Wiatr słoneczny

Earth is still inside a fast solar wind stream, with the continuous arrival of high speed streams (HSSs) from the elongated, posiitve polarity, recurrent coronal hole (SIDC Coronal Hole 128) which started to cross the central meridian on Dec 20. The solar wind speed ranged from 625 km/s to 800 km/s. The interplanetary magnetic field ranged between 2 nT and 7 nT, and the North- South component (Bz) ranged betweeen -6 nT and 5 nT. In the next 24 hours, enhanced solar wind conditions are expected to continue with the further arrival of HSSs from the same coronal hole.

Geomagnetyzm

Geomagnetic conditions were globally at unsettled to active conditions (NOAA Kp 3 to 4), and locally over Belgium at quiet to active conditions (K BEL 2 to 5) during the past 24 hours. We expect unsettled to minor storm conditions (K 3 to 5) in the next 24 hours, possibly with the further arrival of HSSs from the elongated, positive polarity, recurrent coronal hole (SIDC Coronal Hole 128) which started to cross the central meridian on Dec 20.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, exceeded the 1000 pfu threshold for most of the time during the past 24 hours. The electron flux is expected to remain above this alert level during most of the next period. The electron fluence was at moderate levels and is expected to remain so.
