Overview
- The Laboratory of Solar Astronomy at the Space Research Institute (IKI RAN) announced the developing event on November 11 via its Telegram channel, calling it the year's largest and noting it is growing.
- The laboratory’s website lists the flare strength as exceeding X5.0 and continuing to increase at the time of the report.
- RIA Novosti relayed the laboratory’s alert, citing IKI as the source of the real-time observation.
- This surpasses the previous 2025 peak of X2.7 recorded in mid-May, marking a clear escalation in the year’s measured solar activity.
- X-class flares are the most powerful category and can affect satellites, radio communications, and power systems if conditions align, though the cited coverage reports no confirmed terrestrial impacts so far.
