Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was moderate over the past 24 hours, with only C-class flares. The strongest flare was a C3.4 flare (SIDC Flare 5562) peaking at 14:01 UTC on September 25, which was associated with SIDC Sunspot Group 640 (NOAA Active Region 4217, magnetic type beta). There are currently nine numbered active regions on the solar disk. SIDC Sunspot Groups 592, 640, 648, 644, 650 (NOAA Active Regions 4226, 4217, 4230, 4224, 4229) are the most complex, all with magnetic type beta. SIDC Sunspot Group 642 (NOAA Active Region 4221) and SIDC Sunspot Group 647 have rotated over the west limb. The 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: No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery in the last 24 hours. Solar wind: The solar wind conditions (ACE) are gradually returning to the slow solar wind regime, under the waning influence of the high-speed stream from the mid-latitude, negative polarity coronal hole (SIDC Coronal Hole 126). The solar wind speed decreased from approximately 500 km/s to approximately 430 km/s. The interplanetary magnetic field values were mostly around 5 nT. The Bz component varied between -4 nT and 5 nT. The interplanetary magnetic field angle was in the negative sector. Enhanced solar wind conditions are possible over the next 24 hours due to the high- speed stream associated with the small, equatorial, negative polarity coronal hole (SIDC Coronal Hole 132) that crossed the central meridian on September 24. Geomagnetism: Geomagnetic conditions globally and locally were mostly at quiet to unsettled levels (NOAA Kp 1 to 3, K BEL 1 to 3). Unsettled to active conditions are possible over the next 24 hours due to the high-speed stream associated with the small, equatorial, negative polarity coronal hole (SIDC Coronal Hole 132) that crossed the central meridian on September 24. Proton flux levels: The greater than 10 MeV proton flux was below the 10 pfu threshold level over the past 24 hours. It is expected to remain below the threshold level over the next 24 hours. Electron fluxes at GEO: The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 was below the 1000 pfu threshold in the last 24 hours. The greater than 2 MeV electron flux is expected to be below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence is presently at normal levels and is expected to remain so over the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 154,
