Double explosion detected on far side of Sun
A very large double explosion on the far side of the Sun was detected last night. There are still no satellites on the far side, and one can only guess what happened there.
The first strong magnetic storm of 2026 has ended
The first strong magnetic storm of 2026, which simultaneously became one of the largest events of the 21st century, has ended.
The discovery of the first comet of 2026 has been announced. This comet will fall into the Sun on April 4th of this year
The International Astronomical Union has officially announced the discovery of the first comet of 2026, named C/2026 A1 (MAPS).
Geomagnetic indices have returned to levels close to G4
Geomagnetic activity is currently experiencing a renewed increase. The planetary Kp index has returned to a level close to G4 and currently stands at G3.7. This surge is presumably the final one in the current event.
A plasma cloud from the Sun will hit Earth tomorrow at midday
Yesterday\'s early data from the CCOR-1 coronagraph were confirmed today by the world\'s main solar coronagraph, LASCO: the X1.95 flare that occurred was accompanied by a large plasma ejection directed directly at Earth.
The Sun experienced its first X-ray flare of the year
A solar flare of magnitude X1.95 has been registered – the first in 2026 and the largest since November 14, 2025.
A million-kilometer-wide coronal hole has formed on the Sun
Another large coronal hole has formed on the Sun, this time with a rather unusual shape. It resembles a giant upside-down number "1," although with a little imagination, you could probably see a lot more here, just like in the clouds. The "number" is about a million kilometers high.
The second M-flare of the year occurred on the Sun last night
Active region No. 4341, which produced two very powerful explosions on the far side of the Sun in the first two weeks of the year, has emerged onto the side visible from Earth and will become the main source of solar news in the coming days. Last night, the region recorded its second M-class flare of the year.
Geomagnetic activity in the coming year is growing, exceeding the previous record year
The rate of formation of geomagnetic disturbances (Kp index = 4; yellow level) and storms (Kp = 5 and above; red level) in the first 13 days of January exceeded the indicators of the previous year, 2025, which, in turn, were the highest in the last 10–20 years.
The second magnetic storm of January occurred overnight, accompanied by strong auroras
The second magnetic storm of 2026 occurred last night and was accompanied by unexpectedly strong aurora borealis, the lower limit of which in places reached latitudes around 50 degrees. The aurora peaked between 1 and 3 a.m. Moscow time and reached a maximum intensity of 10.
