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 6 numbered sunspot groups were identified on the disk over the past 24 hours, all having alpha or beta magnetic configuration. The largest flare was a M1.7 flare (SIDC Flare 5188) peaking on August 22 at 18:51 UTC from a region behind the east-limb. 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: A halo Coronal Mass Ejection (CME) was detected in SOHO/LASCO-C3 data from 17:12 UTC Aug 22, and will be further analysed when more data become available. A partial halo CME reported by CACTus as launched on 22 Aug at 05:24 UTC is the combination of two CME which are not expected to become geo-effective. Coronal holes: The SIDC Coronal Hole 126 (mid-latitude coronal hole with a negative polarity) is crossing the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on August 26. Solar wind: Slow solar wind conditions were recorded over the past 24 hours, with speed around 460 km/s. The interplanetary magnetic field was around 4 nT, with the Bz reaching a minimum value of -2 nT. Slow solar wind conditions are expected in the next 24 hours. Geomagnetism: Geomagnetic conditions were globally and locally quiet to unsettled (Kp 3 and K Bel 3). Quiet 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): 071,
