Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was moderate with three M-class flares detected during the past 24 hours. NOAA Active Region (AR) 3751 (magnetic type Beta-Gamma-Delta, Catania sunspot group no 12) produced an M2.0 at 19 Jul 18:06 UTC and an M1.8 at 20 Jul 07:20. NOAA AR 3758 (magnetic configuration Beta, Catania sunspot group 93) emitted an M1.0 at 19 Jul 22:51 UTC. NOAA AR 3745 (magnetic configuration Beta, Catania sunspot group no 5) produced the brightest C-class flare of the past 24 hours, a C9 at 20 Jul 00:24 UTC. For the next 24 hours further M-class activity is very likely, and there is a chance of an X-class flare mostly from NOAA AR 3751. Coronal mass ejections: No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. Solar wind: Solar Wind (SW) conditions remained typical of the slow SW regime during the past 24 hours. The SW speed varied between 310 and 400 km/s, while the total interplanetary magnetic field (Bt) ranged between 1 and 10 nT during the past 24 hours. The North-South magnetic component (Bz) fluctuated between -5 and 6 nT, while the interplanetary magnetic field phi angle was directed away and towards the Sun for an almost equal length of time in the past 24 hours. The SW conditions are expected to follow the same pattern for the next 24 hours. Geomagnetism: Geomagnetic conditions were globally and locally quiet during the past 24 hours (NOAA Kp 1+ to 2+ and K BEL 2). They are expected to continue at quiet levels in the next 24 hours. Proton flux levels: The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is likely to remain so. Nevertheless, there is a chance of a proton event associated with the activity of NOAA active region 3751. Electron fluxes at GEO: The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was at nominal levels during the last 24 hours and is expected to remain at these levels during the next 24 hours. The 24h electron fluence was at very low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 234,
