MODEL: Both plasma clouds, including the X-flare ejecta, pass by Earth

Model of plasma ejection motion after the flares of November 3-4, 2025

Both large plasma ejections, the first observed on November 3rd, and the second, main one from yesterday's X1.8 flare, are expected to pass by Earth, according to modeling results.

A computer model of the motion of gas clouds in interplanetary space has now been constructed, taking into account their initial direction and the angles of matter propagation. According to the modeling results, in both cases the matter is deflected from the direction toward Earth by approximately 50-60 degrees and is propagating in a sector with a half-width of approximately 40-45 degrees. It can be noted that the last of the clouds, formed during yesterday's X1.8 flare, will pass very close and, with some probability, will even touch the planet with its edge in 3 days, but, even in this case, the consequences will be minimal.

The modeling results correspond to the most likely scenario. Both active centers responsible for the renewed solar flares emerged from the far side of the Sun just two days ago and are currently still quite far from the center of the visible solar disk, where they would be directly opposite the Earth. The Sun rotates at an angle of 13-15 degrees per day (the exact value fluctuates slightly, as the Sun is not a solid, but a gaseous body). Accordingly, these areas will now be approaching the Earth's direction by this angle every day, and the risks to the planet, unfortunately, will rapidly increase. They will reach their maximum by the weekend. No calculations were made for the nighttime X-ray flare. The event occurred on the far side of the Sun and could not have affected the Earth under any circumstances. The ejected plasma clouds, in this case, would simply fly away from the Earth.
