It peaked at 9:23 p.m. EDT (0123 May 11 GMT), registering as a massive X5.8 class flare, SWPC officials said .

“Solar flares are large explosions from the surface of the Sun that emit intense bursts of electromagnetic radiation, which can last mere minutes. They are rated based on their strength, with A-class as the smallest, followed by B, C, M and X as the most potent, according to the Xinhua News Agency. They are one of the most intense sun phenomena, with a cycle of approximately 11 years. Their main observational characteristics are that a localized region of the solar atmosphere suddenly becomes brighter, often accompanied by enhancements in various energy bands of electromagnetic radiation and particle emissions, with a rapid increase in brightness and a slower decrease”.
