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. A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. The largest flare was a C2.3 flare (SIDC Flare 5184) peaking on August 21 at 15:56 UTC, which was produced by SIDC Sunspot Group 607 (NOAA Active Region 4191). Solar flaring activity is expected to be low over the next 24 hours, with C-class flares likely and a small chance for M-class flares. Coronal mass ejections: No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. Coronal holes: The small SIDC Coronal Hole 127 (polar-north coronal hole with a negative polarity) is crossing the central meridian. The high speed stream from this coronal hole is not expected to enhance the solar wind environment near Earth. Solar wind: The solar wind conditions at Earth remain under the influence of the high speed stream associated with SIDC coronal hole 116. The solar wind speed ranged between 450 to 540 km/s over the past 24 hours. The interplanetary magnetic field is around 4 nT, with the Bz reaching a minimum value of -3 nT. In the next 24 hours, we expect the gradual transition to slow solar wind. Geomagnetism: Geomagnetic conditions were globally and locally quiet to unsettled (Kp 3 and K Bel 3). Quiet to unsettled conditions are expected in the next 24 hours. Proton flux levels: The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days. Electron fluxes at GEO: The greater than 2 MeV electron flux as measured by GOES 18 and 19 remained mainly below the 1000 pfu alert threshold, with a small crossing of the threshold around 17:00 UTC. The greater than 2 MeV electron flux is expected to remain mainly below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 054,
