Состояние солнечной активности на 25 августа 2025, 1230UT
Прогноз SIDC
Солнечные вспышки. Ожидаются вспышки класса M (вероятность >=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 25 августа 2025: Солнечный поток в диапазоне 10см: 152 / AP-индекс: 007
Прогноз на 26 августа 2025: Солнечный поток в диапазоне 10см: 156 / AP-индекс: 016
Прогноз на 27 августа 2025: Солнечный поток в диапазоне 10см: 160 / AP-индекс: 007
Комментарий (на английском языке): Solar Active Regions and flaring: Solar flaring activity was moderate over the past 24 hours, with 2 M-class flares identified. They both originated at a (yet) unnumbered region rotating into view over the east limb (close to the equator). The largest flare was an M4.5 flare peaking at 05:24 UTC. Most of the flaring activity (including several C-class flares) is located on the eastern hemisphere of the Sun. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares likely and a small chance for X-class flares. Coronal mass ejections: No Earth-directed Coronal Mass Ejections (CMEs) have been observed in the last 24 hours. Coronal holes: SIDC Coronal Hole 126 (northern mid-latitude coronal hole with negative polarity) is located in the western hemisphere and its related high speed solar wind streamm may arrive to the Earth on 26 August. Solar wind: The Earth is inside slow solar wind with speeds around 410 km/s and interplanetary magnetic fields of about 8 nT (directed towards the Sun, negative polarity). In about 24 hours, the arrival of a high speed stream is expected. Geomagnetism: Geomagnetic conditions have been quiet (Kp and B_Bel between 0 and 2). Similar conditions are expected until the arrival of the high speed solar wind stream on 26 August (mostly active conditions expected then). Proton flux levels: The greater than 10 MeV proton flux has been slowly and gradually increasing since 22 August, and it is now close to the 10 pfu threshold. A warning condition forecast is issued for the next 48 hours. Electron fluxes at GEO: The greater than 2 MeV electron flux as measured by GOES 18 and 19 remained below the 1000 pfu alert threshold (except for a minimal crossing of the threshold around 16:00 and 23:00 UTC on 24 August), similar conditions expected for the next 24 hours. The 24 h electron fluence was at normal levels and is expected to remain so.Сегодняшнее значение числа солнечных пятен (International Sunspot Number): 136,
