Scientists at the Laboratory of Solar Astronomy, part of the Space Research Institute (IKI) of the Russian Academy of Sciences, have reported a significant and sustained increase in solar activity. Over the past three months, the sun`s activity cycle has shown consistent growth, escalating by nearly 70% since May 2025 and returning to the levels last observed at the beginning of 2024.
This notable surge is consistent with patterns observed in the two preceding solar cycles of the 21st century. Researchers noted that both of these earlier cycles exhibited two distinct peaks of comparable intensity, typically separated by an interval of approximately 1.5 to 2 years. This historical context provides a framework for understanding the current upward trend.
The scientific community is now closely monitoring the sun`s behavior, with particular interest focused on the anticipated levels of solar activity during the upcoming autumn season. This period is expected to offer crucial data and insights into the trajectory of the current solar cycle.
