End of the solar maximum: what awaits Earth in the coming years

The Sun is on the decline: Russian astronomers announce the end of our star's peak activity

Russian scientists have made an important statement about the condition of our star. According to specialists' observations, the Sun has passed the peak of its activity in the current cycle and is now entering a phase of gradual quieting. This conclusion was voiced by Leonid Ledentsov, a candidate of physical and mathematical sciences, temporarily heading the Solar Physics department at the Sternberg State Astronomical Institute of Moscow State University.

The scientist noted that although on average the solar cycle lasts about 11 years, this is only a statistical value, and the actual duration can fluctuate significantly. Astrophysicists acknowledge that precisely determining the moment of maximum solar activity is not a simple task.

"Apparently, at this point, the peak of the 25th solar activity cycle has passed, and the declining branch is beginning. If this statement proves to be correct, then the peak of activity occurred in mid-2024," Ledentsov emphasized.

According to the expert's forecasts, in the coming years, solar activity will gradually decrease until it reaches a minimum. After this, a new, 26th cycle will begin. Interestingly, systematic observations of the Sun have been conducted since March 1755 — that's when the first solar cycle was recorded.

Ledentsov also explained an important nuance: not every manifestation of solar activity causes coronal mass ejections, just as not all groups of sunspots lead to flares. To affect Earth, a solar ejection must not only occur but also be directed toward our planet. All these factors are carefully analyzed when compiling space weather forecasts.

Recall that on the night of May 29, a strong magnetic storm, close to class G3, was recorded on Earth. Magnetic storms are classified on a five-point scale: from G1 (weak) to G5 (extremely strong). Strong geomagnetic disturbances can affect the operation of satellite systems, including GPS, temporarily reducing the accuracy and reliability of navigation.
