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. A total of 7 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 M1.1 flare (SIDC Flare 5177) peaking on August 19 at 04:39 UTC, which was produced by SIDC Sunspot Group 572 (NOAA Active Region 4188), who has a Alpha 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 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: The solar wind conditions at Earth were mainly slow over the past 24 hours. The speed started to increase slightly from 350km/s to 420 km/s. The interplanetary magnetic field reached a maximum of 16 nT with the Bz reaching a minimum value of -7 nT. The solar wind speed is expected to become enhanced in the next 24 hours, due to the potential arrival of the high-speed stream (HSS) associated with the SIDC coronal hole 116. Geomagnetism: Geomagnetic activity was quiet to unsettled over the past 24 hours both globally and locally. In response to the expected arrival of high-speed stream, geomagnetic conditions are expected to reach active level 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 measured by GOES 18 and GOES 19 has dropped below the 1000 pfu threshold. Electron flux levels are expected to remain below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence returned to normal levels and is expected to remain so over the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 038,
