Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C6.9 flare (SIDC Flare 6493) peaking on December 26 at 09:14 UTC which was produced by an unnumbered group in the SE limb. A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 740 (NOAA Active Region 4321) is the most complex region with its Beta-Delta magnetic configuration and was growing 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: No Earth-directed coronal mass ejections (CME) were detected in the available coronagraph observations during last 24 hours. Solar wind: Over the past 24 hours, solar wind parameters continued to reflect the waning influence of a high-speed stream (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 decreased from 635 km/s to 485 km/s. The interplanetary magnetic field ranged between 0 nT and 7 nT, and the North-South component (Bz) ranged betweeen -5 nT and 5 nT. In the next 24 hours, enhanced solar wind conditions are expected to continue with the waning influence of HSSs. Further enhancements are possible if a glancing blow, associated with a coronal mass ejection (CME) that was observed lifting from the Sun on Dec 22 (SIDC CME 615), arrives late. Geomagnetism: Geomagnetic conditions were globally at quiet (NOAA Kp 1 to 2), and locally over Belgium at quiet to unsetlled conditions (K BEL 1 to 3) during the past 24 hours. In the next 24 hours, we expect quiet to unsettled conditions (K 1 to 3) unless glancing blow, associated with a coronal mass ejection (CME) that was observed lifting from the Sun on Dec 22 (SIDC CME 615), arrives late and enhances the geomagnetic conditions to active to minor storm conditions (K 4 to 5). 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: The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, was above the 1000 pfu threshold for most of the time during the past 24 hours. It was in response to the high speed streams (HSS) from the southern, positive polarity, recurrent coronal hole (SIDC Coronal Hole 128) which started to cross the central meridian from Dec 20. 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.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 117,
