The first magnetic storm of December 2025 is expected today, the 3rd. It is caused by a combination of several factors affecting Earth: another coronal hole currently observed in the central part of the solar disk, and the plasma ejection from the X-level flare that occurred on December 1st.

The Sun continues to display one of the largest sunspot complexes in recorded history, formed from three regions numbered 4294, 4296 and 4298.

A giant sunspot complex consisting of three groups—4294, 4296, and 4298—that appeared on the southeastern edge of the Sun a few days ago continues to break records. The total area of the complex, which, despite being artificially divided into three numbers in the catalog, physically represents a single structure, exceeded 2,000 units this morning, reaching 2,200 units.

The southern sunspot group, which approached Earth two days ago, has reached its largest size this year. The total area of the complex, measured at the beginning of the day, is 1,600 units, which is currently about 60% of the size of the largest sunspot groups of the 21st century (approximately 2,800 units), but already a third larger than the previous annual record of 1,200 units, achieved in May 2025 (region No. 4079).

Solar flares of the highest X-level have resumed. Early this morning at 05:49 Moscow time, a new X1.9 event was registered on the northeastern edge of the Sun after a two-week hiatus (since November 14).

The video shows the first of two expected large active regions approaching Earth - region 4294, located in the south. The sunspot group currently has an area of 800 units, making it the third largest this year.

As 3I/ATLAS moves away from the Sun, as expected, increasingly high-quality photographs of the object are beginning to arrive, revealing some previously hidden (or missing) details. The most remarkable of these is undoubtedly the anti-tail, oriented opposite to the main normal tail.

A noticeable increase in activity is observed on the far side of the Sun. In a few days, new major active centers may appear in Earth's field of view.
25.11.2025
The planet has been passing through a fast plasma stream formed in the coronal hole on the Sun for the second day and unexpectedly, two days earlier than expected, it reached Earth yesterday.
25.11.2025
The close approach of 3I/ATLAS to Jupiter, the solar system's largest planet, which has been widely discussed in recent days, is expected to occur on March 16 of next year at approximately 3:00 PM Moscow time. The object will pass just over 53 million kilometers from the gas giant, marking its last close encounter with any planet in the solar system.
