Прогноз SIDC
SOLAR FLARES : C-class flares expected, (probability >=50%)
Геомагнитное поле: Спокойное состояние (A<20 and K<4)
Солнечные протоны: Ожидается увеличение возмущенности (уровни активности повысятся,
но точного числового прогноза нет)

Прогноз на 19 ноября 2025: Солнечный поток в диапазоне 10см: 132 / AP-индекс: 011
Прогноз на 20 ноября 2025: Солнечный поток в диапазоне 10см: 132 / AP-индекс: 014
Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 693 (NOAA Active Region 4284) currently located at S07W22 (Beta-Gamma magnetic configuration) was the most complex and active region over the past 24 hours. The largest flare was a C6.1 flare (SIDC Flare 6124) peaking on November 17 at 16:06 UTC from behind the west limb (SIDC Sunspot Group 687 /NOAA Active Region 4274). Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a small chance for M-class flares. Coronal mass ejections: No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images. Coronal holes: SIDC Coronal Hole 136 (mid-latitude coronal hole with a negative polarity) finished it's crossing of the central meridian. SIDC Coronal Hole 137 (mid-latitude coronal hole with a negative polarity) crossed the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on November 21. Solar wind: Slow solar wind conditions were recorded over the past 24 hours. The interplanetary magnetic field was around 6 nT and 13 nT, with the Bz reaching a minimum value of -3 nT. The solar wind velocity further decreased to 458 km/s. Slow solar wind conditions are expected in the next 24 hours. Geomagnetism: Geomagnetic activity was active globally and locally quiet to unsettled over the past 24 hours. Geomagnetic conditions are expected to remain quiet to unsettled in the next 24h. Proton flux levels: The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days. Electron fluxes at GEO: The greater than 2 MeV electron flux measured by GOES 18 remained below the 1000 pfu threshold, and the 2 MeV electron flux measured by GOES 19 shortly crossed the 1000pfu threshold on Nov 17 at 19:30 UTC. Electron flux levels are expected to remain below the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence remains at normal levels and is expected to remain at normal levels over the next 24 hours.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 066,
