Astronomers from the Space Research Institute of the Russian Academy of Sciences and the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences reported a second major plasma ejection on the Sun. According to the Solar Astronomy Laboratory, the event was recorded on Thursday night and classified as an M8.65 flare — almost the maximum strength for the average range of solar flares.
The maximum solar activity was recorded on November 6, 2025 at 01:07 Moscow time. This ejection followed immediately after the previous one, which occurred the day before, and developed at a colossal speed — about 1,000 kilometers per second. Scientists note that the second plasma flow turned out to be more massive and faster: it will catch up with the first one in space, partially "absorbing" it.
According to experts' calculations, the consequences of this double burst of solar activity will reach Earth on Friday. As a result, an increase in geomagnetic disturbances and the occurrence of a magnetic storm are possible, which may affect radio communications, navigation systems, and power grids. The exact forecast of the storm level will be updated on the night of November 7.
Such flares occur when the accumulated energy of magnetic fields is abruptly released in active regions of the Sun. As a result, powerful flows of plasma — charged particles — are ejected into space, which, reaching Earth, interact with the magnetosphere and cause auroras.
