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 4 numbered sunspot groups were identified on the disk over the past 24 hours, having all Alpha or Beta magnetic configuration. The largest flare was a C2.9 flare (SIDC Flare 5179) peaking on August 20 at 09:30UTC, from SIDC Sunspot Group 607 currently located at N10E90 (Alpha magnetic configuration). 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. Solar wind: Fast solar wind conditions were recorded over the past 24 hours, following the arrival of the High Speed Stream associated with SIDC Coronal Hole 116. The speed increase to mainly 620 km/s with a peak at 688 km/s. The interplanetary magnetic field gradually decreased from 20 nT to 4nT, with the Bz reaching a minimum value of -11 nT. The solar wind speed is expected to remain fast in the next 24 hours. Geomagnetism: Over the past 24 hours, the geomagnetic activity was mainly active, with a isolated period of minor storm, both globally and locally, due to the arrival of the high speed stream. Active geomagnetic 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 remained below the 1000 pfu alert threshold, and is expected to remain 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): 056,
