Scientists predict the onset of a period of extremely powerful solar flares
Researchers have observed a sharp increase in the likelihood of extremely powerful solar flares, which could significantly disrupt the operation of Earth-orbiting satellites, ground-based power grids, and future space missions.
According to experts’ forecasts, the most risky and dangerous periods for global infrastructure are expected between 2025 and 2027.
A group of scientists led by the National Autonomous University of Mexico has proposed a new system for forecasting high-class flares, whose intensity exceeds the X10 level on the standard scale.
According to the researchers, within the current 25th solar cycle, the Sun may already be approaching an extreme-level flare.
A thorough analysis of data from 1975 to 2025, obtained from environmental monitoring satellites, identified 37 S-class superflares in previous cycles.
Instead of attempting to pinpoint the exact moment of the flare, scientists focused on a probabilistic model that allows for the identification of periods and regions on the Sun with an increased risk.
During the analysis, two recurring solar rhythms were identified—approximately 1.7 years and about 7 years—associated with plasma oscillations.
When these two natural cycles coincide in their active phases, the overall probability of superflares occurring on the Sun increases sharply.
According to the latest calculations by astrophysicists, two distinct time windows of increased risk for Class S superflares are clearly identified in the current solar cycle.
The first dangerous phase lasts from mid-2025 to mid-2026, and the next is predicted for early to mid-2027.
Experts emphasize that such extreme space phenomena are capable of massively disrupting satellite systems, power grids, and communications, as well as directly threatening the lives and health of astronauts.
In May 2026, several periods of solar activity are expected, which may affect the well-being of weather-sensitive people and the operation of electronic devices.
May 2026 marks a turning point in the year. While April gave us the “green light” for all endeavors, May calls for caution.
