A star that had been completely devoid of energy for the past two weeks has suddenly begun to revive somewhat. This morning, a fairly large double prominence was detected, occurring simultaneously at the Sun's north and south poles.

As expected the day before, a magnetic storm has begun on Earth. The current level is G1: the minimum on a five-point scale. The total duration of the unstable geomagnetic period could be quite significant, from 5 to 7 days, but the acute phase is expected to last only the first 1-2 days and extend through the weekend.

Calculations indicate that by the end of today, the stream of fast solar wind that is currently forming in a large coronal hole on the Sun will overtake the Earth, triggering a period of approximately 2-3 days of unstable geomagnetic conditions.

Solar activity continues to decline. The solar background X-ray emission (flare graph) has been below level "C" for about a week. This means that the solar corona, as a whole, is entering an increasingly quiet state.

A previously unknown comet is currently falling toward the Sun along the same trajectory that Comet C/2026 A1 took on April 4 and burned up in the solar atmosphere.

A fairly strong surge in solar activity that was observed on April 4-5 (more than 30 flares occurred in 2 days, including 4 M-level events) has completely ended without any significant consequences

Comet C/2026 A1 has not returned to the field of view of space observations, having vanished yesterday around 2:30 PM Moscow time due to its proximity to the Sun. This means the celestial body no longer exists—it has been absorbed by the Sun, becoming part of it.

The comet is currently 3.6 million kilometers from the Sun's surface (4.3 million kilometers from its center). The rapid decay of the celestial body continues—the nucleus is rapidly shrinking, and, as a result, the tail formed by the nucleus is also thinning.

As of 12:00 Moscow time, the comet is approximately 5 million kilometers from the Sun. Judging by images from the CCOR-1 space-based coronagraph (the only one transmitting relevant data in recent hours), the comet's nucleus is no longer able to resist the thermal currents and the increasing drag of the solar atmosphere and has begun to disintegrate. Images from the last hour clearly show the separation of the head of the nucleus from the tail.

The demise of comet C/2026 A1 will likely only be visible via spacecraft. The celestial body's brightness increases as it approaches the Sun, but much more slowly than predicted.
