[Regnum] On the night of November 1, four powerful flares occurred on the Sun, the Institute of Applied Geophysics (IPG) reported.
One of the flares was close to the highest class X.
“On November 1 at 00:54 Moscow time, an M9.5 flare lasting 55 minutes was recorded in the X-ray range in the sunspot group 3878 (N15E26),” the IPG reported.
In turn, the X-ray Astronomy Laboratory of the Sun of 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 recalled that region 3878, during its last passage across the disk, produced a magnetic storm of level G4.66 on October 11, 2024.
"The storm was the second most powerful in the entire 25th solar cycle. The maximum radiation of the flare was recorded near the Earth's orbit at 00:20 Moscow time. Based on the results of measuring the X-ray flux, the event was assigned the score X2.0," the laboratory reported.
Scientists noted that the X2.0 event "does not look threatening," but the "reputation" of 3878, which on October 11 "managed to squeeze out the second most powerful magnetic storm in seven years from an X1.8 flare," is alarming.
As reported by the Regnum news agency, on October 9, a level X flare occurred on the Sun. It caused a plasma ejection towards the Earth and a magnetic storm. As scientists noted, the plasma was ejected exactly along the Sun-Earth line, the geometric dimensions of the ejection exceeded possible calculation errors.
A plasma cloud with a speed of about 600 km/s and a temperature of about 700 thousand degrees reached the Earth on October 28. Two active spots 3842 and 3848 are located on the side of the Sun visible from Earth. They caused powerful magnetic storms at the beginning of the month.
