Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was low over the past 24 hours, with five C-class flares identified. SIDC Sunspot Group (SG) 706 (NOAA Active Region [AR] 4291, Beta-Gamma magnetic configuration) and SIDC SG 707 (NOAA AR 4292, Beta-Gamma magnetic configuration) produced all the flaring activity. The brightest flare of the past 24 hours was SIDC flare 6207, a C2, that peaked on 27 Nov at 00:47 UTC and is associated with SIDC SG 706. More C-class flaring activity is expected in the next 24 hours, mostly from SIDC SG 706. Coronal mass ejections: No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours. Solar wind: Over the past 24 hours, solar wind parameters (ACE and DSCOVR) reflected the waning influence of a high-speed stream (HSS). The solar wind speed gradually decreased from about 700 km/s to 630 km/s. The interplanetary magnetic field (B) varied between 2 and 8 nT and its North- South component (Bz) fluctuated between -6 and 6 nT. The SW speed is expected to continue its slow decline and the magnetic field is expected continue at similar levels in the next 24 hours. Geomagnetism: Geomagnetic conditions registered globally minor storm levels for a short period of time (NOAA Kp 5- on 27 Nov from 09:00 to 12:00 UTC) while the rest of the past 24 hours varied between unsettled and active conditions (NOAA Kp 3 to 4). Locally minor storm conditions (K BEL 5) also registered but for a different time interval (26 Nov 15:00-18:00 UTC). Quiet to active conditions prevailed locally for the remaining of the past 24 hours. Active and possibly minor storm conditions are expected 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 above the 1000 pfu threshold during the past 24 hours with a peak value of 10000 pfu on 16 Nov at 15:30 UTC. The electron flux is expected to continue exceeding this threshold over the next day. The 24-hour electron fluence was at moderate levels during the past 24 hours and is expected to remain at moderate levels over the next day.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 091,
