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 C4.0 flare (SIDC Flare 5451) peaking on September 07 at 18:13 UTC, which was produced by SIDC Sunspot Group 631 (NOAA Active Region 4213). During the flare, the source region (AR 4213) of the flare had beta configuration of its photospheric magnetic field. A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Groups 624, 628, and 631 (NOAA Active Regions 4207, 4210, and 4213 ) are the complex regions with its beta magnetic configurations. The solar flaring activity is expected to be at low to moderate levels over the next 24 hours with C-class flares expected and a chance for M-class flares. Coronal mass ejections: No Earth-directed coronal mass ejections were detected in the available coronagraph observations during last 24 hour. Solar wind: Over the past 24 hours, the solar wind parameters remained under the influence of high speed streams (HSSs) from the SIDC Coronal Hole 123 (positive polarity, elongated coronal hole in the southern hemisphere) which started to cross the central meridian on Sep 02. The solar wind speed ranged from 470 km/s to 640 km/s. The North-South component (Bz) ranged between -6 and 7 nT. The interplanetary magnetic field ranged between 3 nT to 9 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 at quiet to active conditions (NOAA Kp 0 to 4), globally and at quiet to unsettled conditions locally during the past 24 hours. It was due to the influence of high speed streams (HSSs) from the SIDC Coronal Hole 123 (positive polarity, elongated coronal hole in the southern hemisphere) which started to cross the central meridian on Sep 02. In the next 24 hours, quiet to active conditions (K 1 to 4) are possible with the continuous 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: The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites, were below the 1000 pfu threshold in the past 24 hours. It may cross the threshold during the next 24 hour. The 24-hour electron fluence was at normal levels and is expected to remain at so over the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 118,
