Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was low over the past 24 hours, with four C-class flares identified. This brightest flare was SIDC Flare 5683, a C3 detected on 5 Oct at 23:42 UTC. It is located at the west limb at N10 and probably partially obstructed by the limb. The same location also produced a C2 on 6 Oct at 08:55 UTC. SIDC Sunspot Group 663 (NOAA Active Region [AR] 4242, Beta magnetic configuration) emitted a C2 on 6 Oct at 10:00 UTC. SIDC Sunspot Group 661 (NOAA AR 4241, Beta magnetic configuration) produced a C1 on 6 Oct at 08:49 UTC. Solar flaring activity is expected to be very low over the next 24 hours, with a chance for C-class flares. Coronal mass ejections: No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. Solar wind: The Solar Wind (SW) conditions returned to a slow SW regime during the past 24 hours. The SW speed dropped from 520 to 400 km/s, while the interplanetary magnetic field (B) ranged between 2 and 7 nT, and its North-South component (Bz) fluctuated between -4 and 5 nT. A similar pattern is expected for the next 24 hours, although there is the possibility of a glancing blow associated with SIDC CME 570. Geomagnetism: During the last 24 hours geomagnetic conditions were both globally and locally quiet (NOAA Kp 1- to 2+ and K BEL 1 to 2). They are expected to remain at the same level, both globally and locally, for the next 24 hours. Proton flux levels: The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours. Electron fluxes at GEO: The greater than 2 MeV electron flux as measured by GOES 19 was well above the 1000 pfu threshold during the past 24 hours, with a peak value at 24000 pfu. It is expected to remain at the current levels during the next 24 hours. The 24-hour electron fluence is at high levels since 4 Oct 23:10 UTC and is expected to continue at high levels for the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 164,
