Intense solar flares have occurred in various years, including

the Carrington Event in 1859, the Halloween storms in 2003, and a major event in May 2024, which was the most powerful solar storm to reach Earth in two decades. Other notable flares occurred on April 2, 2001, and September 6, 2017. 

• 1859: The Carrington Event is considered one of the most powerful solar storms in recorded history. It caused telegraph systems to fail and sparked auroras so bright they were visible at night in the Caribbean.
• 2003: The "Halloween storms" included several intense flares, with the largest, an X28-class flare, occurring on November 4, 2003, which was the most powerful flare ever recorded at the time.
• 2001: A large X20 flare peaked on April 2, 2001.
• 2017: An X9.3 flare occurred on September 6, 2017, causing significant radio blackouts.
• 2024: A barrage of flares and coronal mass ejections in May 2024 created the strongest solar storm to reach Earth in two decades.
• Recent events: Another intense X-class flare occurred on November 11, 2025.
