[1][2][3] This series of storms generated the largest solar flare ever recorded by the GOES system, modeled as strong as X45 (initially estimated at X28 due to saturation of GOES' detectors).

[4][5] Satellite-based systems and communications were affected, aircraft were advised to avoid high altitudes near the polar regions,[6] and a one-hour-long power outage occurred in Sweden as a result of the solar activity.

[6] Twelve transformers in South Africa were disabled and had to be replaced, despite the country's low geomagnetic latitude.

[7] The SOHO satellite failed temporarily and the Advanced Composition Explorer (ACE) was damaged by the solar activity.

[6] Astronauts aboard the International Space Station (ISS) had to stay inside the more shielded parts of the Russian Orbital Segment to protect themselves against the increased radiation levels.
