Комментарий (на английском языке): Solar Active Regions and flaring: The solar flaring activity was at moderate level during the last 24 hours, with few C-class flares and two M-class flares. The strongest flare was GOES M1.7 flare from NOAA active region (AR) 3761 which peaked at 04:42 UTC on Jul 26. During the flare, the source region (AR 3761) of the flare had beta-gamma configuration of its photospheric magnetic field. Currently, NOAA AR 3762 is the most complex region on the disk (beta-gamma-delta magnetic field configuration), but it has only produced C-class flarings. The solar flaring activity is expected to be at moderate to high levels over the next 24 hours, possibly with few M-class flares and a low chance for isolated X-class flares. Coronal mass ejections: No Earth-directed CMEs were detected in the available coronagraph observations during the last 24 hour. Solar wind: Earth was under the influence of sector boundary crossing followed by the fast wind reaching a maximum speed value of 610 km/s. Presently, the solar wind speed amounts about 520 km/s. The solar wind speed ranged between 370 km/s and 600 km/s. The North-South component (Bz) ranged between -13 and 16 nT. The interplanetary magnetic field ranged between 2 nT and 20 nT. Enhanced solar wind parameters are expected in the next 24 hours, due to the possible arrival of an interplanetary coronal mass ejection associated with a halo CME that was observed lifting from the Sun on Jul 25. Geomagnetism: Enhanced solar wind speed of upto 560 km/s and negative value of the interplanetary magnetic field component Bz, down to -10 nT, induced a disturbed geomagnetic conditions due to the sector boundary crossing. Geomagnetic conditions were globally at quiet to minor storm conditions (NOAA Kp 1 to 5) and locally at quiet to active conditions (K BEL 2 to 4). We expect active to moderate storm conditions (K 4 to 6) in the next 24 hours due to the possible arrival of an ICME, associated with a halo CME that was observed lifting from the Sun on Jul 25. Proton flux levels: The greater than 10 MeV GOES proton flux was below the threshold level over the past 24 hours. It is expected to remain so during the next 24 hours. A major flare from NOAA active regions which are presently close to and at the W limb, in the coming hours, could be possibly associated with a proton event. Electron fluxes at GEO: The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the threshold level over the past 24 hours and is expected to remain so in the coming 24 hours. The 24h electron fluence is presently at low level, and it is expected to be at low to normal level in the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 198,
