The second most powerful solar flare of the year X4.05 occurred on the Sun.

Another major explosion was recorded on the Sun this morning. At 11:30 Moscow time, an X4.05 flare occurred. The epicenter of the event was once again region 4274, located in the Sun's northern hemisphere, which just two days ago produced an X5.15 flare—the most powerful event of the year, responsible for the magnetic storm of November 11-13 (the second-strongest in five years).

The amount of energy in this region of the Sun appears completely inexplicable. The active center is relatively modest in size, which is poorly correlated with the power and number of explosions produced there. Powerful flares in the center began two or three weeks ago, when it was on the far side of the Sun, and apparently contributed to the change in the motion of the object 3I/ATLAS, which was directly hit by ejected plasma clouds. Since then, explosive activity in the center has essentially continued. Following several very powerful explosions on the far side of the Sun, the region, having reached Earth, produced five consecutive high-level X flares (the first since June 2025), and has now produced a sixth. Contrary to expectations, the explosions are not subsiding, but rather escalating. The last two events, including today's, were the first and second most powerful flares of the year. Against this backdrop, the theory that an "alien ship" dropped something onto the Sun from the far side, triggering, for reasons known only to itself, a series of the most powerful flares of the year, is likely to gain further traction on forums and chats among proponents of the extraterrestrial nature of the 3I/ATLAS object.

At this time, we rule out the possibility of a noticeable impact of this new event on Earth, despite its unusual power. Two days have passed since the X5.15 flare. During this time, the active center should have moved an additional 30 degrees away from Earth. This reserve should be sufficient to ensure that even potential large ejections miss the planet. The possibility of a marginal impact is still possible, but a repeat of the recent strong storm is no longer possible. Only weak and moderate impacts are possible.

Information on geomagnetic consequences will be available later. At this point, the flare itself hasn't even fully ended.
