Earth is on track to record its highest number of magnetic storm days in a decade, Russian scientists have said.
The Laboratory of Solar Astronomy at the Space Research Institute of the Russian Academy of Sciences said Earth has experienced 69 days with magnetic storms so far this year, up from 44 days in 2024.
The rise is even sharper in the number of days with geomagnetic disturbances, which reached 164 in 2025 compared with 94 last year.
Similar levels were last seen in 2015, when 79 magnetic storm days were recorded, and in 2016, which saw 69 such days.
Scientists said the 2016 figure will almost certainly be surpassed in the final week of the year, as a large coronal hole on the Sun continues to influence Earth.
