Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was a M1.3 flare (SIDC Flare 6467) peaking on December 21 at 18:27 UTC, which was produced by SIDC Sunspot Group 731 (NOAA Active Region 4316). A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. 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. Coronal mass ejections: A wide CME (~110 deg) on NE was first observed in SOHO/LASCO-C2 images around 05:00 UTC on Dec 22. This was possibly associated with the flaring activity from SIDC Sunspot Groups 735 and 736 (NOAA Active Region 4317). A glancing blow associated with this CME is possible at Earth but not very probable. No other Earth-directed CMEs were detected in the available coronagraph observations during last 24 hours. Solar wind: Over the past 24 hours, the solar wind parameters remained under the influence of high speed streams (HSSs) from the southern, positive polarity coronal hole (SIDC Coronal Hole 128) that has been crossing the central meridian since December 20. The solar wind speed ranged from 520 km/s to 840 km/s. The North-South component (Bz) ranged between -12 and 7 nT. The interplanetary magnetic field ranged between 3 nT to 14 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. Geomagnetism: Geomagnetic conditions were globally at unsettled to minor storm conditions (NOAA Kp 3 to 5), and locally over Belgium at quiet to minor storm conditions (K BEL 2 to 5) during the past 24 hours, possibly as the result of the ongoing influence of high speed streams (HSS) from the southern, positive polarity, recurrent coronal hole (SIDC Coronal Hole 128). 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 same coronal hole. Proton flux levels: 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. Electron fluxes at GEO: Over the past 24 hours, the greater than 2 MeV electron flux, as measured by GOES-18 satellite, exceeded above the 1000 pfu threshold level from 18:10 UTC on Dec 21 and finally dropped below the threshold around 00:10 UTC on Dec 22. The greater than 2 MeV electron flux, as measured by GOES-19 satellite, exceeded above the threshold level from 14:20 UTC to 16:10 UTC on Dec 21. In the next 24 hours, the electron flux may exceed the threshold level again. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 083,
