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

That night, while everyone in the European part of the country and the continent was asleep (though some were probably still awake), instruments recorded a second consecutive X-level solar flare. The interval between the peaks of the first and second events was approximately 4.5 hours. The maximum radiation was recorded at 1:01 AM Moscow time. The previous flare was detected the day before, on November 4, with a peak at 8:34 PM.

The Sun experienced an X-class flare, observed for the first time after a nearly 5-month hiatus that began in June 2025. The last time a top-level event (X1.9) was recorded was on June 19, 2025.

This video, unpresentable by today's standards, taken 22 years ago by the European spacecraft SOHO, shows the most powerful solar flare of the first quarter of this century. The event occurred on November 4, 2003, at 10:53 PM Moscow time.

The Sun continues to exhibit two large centers of activity emerging onto the side visible from Earth, both of which are returning to the planet again. These groups previously crossed the solar disk in mid-October, after which, due to the Sun's rotation, they moved beyond the right (western) horizon.

We are publishing a unique video showing the movement of the object 3I/ATLAS near the Sun. We obtained the video using data from the LASCO/C3 coronagraph, a highly sensitive instrument designed specifically to observe faint objects near the solar disk, precisely where 3I/ATLAS, which arrived from other stars, is currently hiding from observation.

Today, this afternoon, according to calculations, the 3I/ATLAS object will be struck by one of the largest plasma clouds in Solar Cycle 25 (https://t.me/lpixras/1660), ejected by the Sun toward the comet on the night of October 21-22. There is a high probability that this will be the first such test in the life of a celestial body, with consequences that are not fully understood.

The interstellar object 3I/ATLAS will likely remain invisible from Earth until at least mid-November
The interstellar wanderer 3I/ATLAS remains invisible to Earth. In the second half of September, the comet approached the Sun so closely that it was completely obscured by its rays. Currently, the object is projected onto the sky at a minimal distance from the solar disk and is effectively a daytime, rather than a nighttime, object: it is located in the sky near the Sun during daylight hours.

The plasma cloud ejected by today's explosion is estimated to be pointed precisely (within 10-20 degrees) in the direction of 3I/ATLAS, which is currently passing on the opposite side of the Sun with a slight shift to the northwest.

The first major spike of activity in the new 25th cycle on the Sun has ended. The peak of solar flares came on the 29th of May. The total flare activity index reached a maximum of 4.4 on 10-point scale, which corresponds to the top of the yellow level on the scale of the solar flares activity. Until the next, orange level, starting with a score of 5, the event lacked only 0.6 points.
