Solar activity is in a declining phase, and the peak of the current, 25th solar cycle, has passed. This was reported by the Laboratory of Solar Astronomy of IKI RAN and ISZF SB RAS.
The data received in May 2025, apparently, finally confirm that the maximum of the current 25th cycle has passed. Solar activity is currently in a pronounced stage of decline, which, tentatively, will end only around 2030.
The sunspot number index (the main indicator for measuring the solar cycle) sharply decreased last month to the minimum value since August 2022 and amounted to 79 units, while in April it remained around 140 units.
Despite the decline in solar activity, scientists emphasize that this phase will still be accompanied by the risk of major flares and magnetic storms until at least 2027.
Earlier www1.ru reported that one of the strongest plasma ejections in recent years was recorded on the Sun.
