[Regnum] Scientists have recorded a resumption of strong solar flares two weeks after a hiatus. This was reported on Sunday, November 2, by the Solar Astronomy Laboratory of the Space Research Institute (IKI) of the Russian Academy of Sciences.
"The Sun is experiencing a resumption of strong flare activity, last observed in mid-October and interrupted for two weeks," the laboratory's website states.
According to scientists, a level 4 M1.0 (strong) flare, measured on the five-level solar physics scale, was observed on the eastern edge of the Sun on the night of November 2. It occurred from 3:26 AM Moscow time to 3:37 AM Moscow time and will not impact Earth.
Yesterday, the active solar region 4246 fully emerged onto the visible side of the sun. According to scientists, flares from this region could impact Earth next week.

Russian Academy of Sciences Astronomy Laboratory: 3I/ATLAS acceleration may be caused by solar flares
The non-gravitational acceleration of the interstellar object 3I/ATLAS may be related to solar flares. This was reported on November 2 by the Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences.
"The additional non-gravitational acceleration of the interstellar object 3I/ATLAS, which has been reported, may be due to the impact of plasma clouds ejected by the Sun approximately 10 days ago as the object approached perihelion," the laboratory reported on its Telegram channel.
From October 23 to 27, the object should have been hit by at least five large solar ejections, especially on October 24, since two days before that, an X flare occurred on the far side of the Sun.
Scientists have ruled out the direct transfer of a noticeable impulse from solar plasma to the comet's nucleus, since, due to its low density, the solar wind has almost no direct kinetic effect on bodies immersed in it.
"However, solar plasma at such temperatures (up to 1 million degrees) should have disrupted the dynamics of the comet's tail and could also have affected the outflow of gas and dust from the body's surface. It is the latter that generates the non-gravitational jet thrust that differentiates cometary flight from the purely ballistic motion of ordinary asteroids around the Sun," the laboratory noted.
Scientists recalled that active solar centers appeared in Earth's field of view on November 1st, influencing 3I/ATLAS in the second half of October. They will likely "test the Earth's resilience" in the coming days. Satellites near Earth began recording the first strong flares this morning.
