A major solar flare measuring X5.8 erupted from Active Region 3664 at 01:23 UTC on May 11, 2024. The event started at 01:10 and ended at 01:39 UTC. It took place during G5 \u2013 Extreme geomagnetic storm, producing another CME \u2014 most likely Earth-directed.<\/strong><\/p>\n Today\u2019s X5.8 is the second strongest solar flare of the current solar cycle \u2014 Solar Cycle 25 \u2014 after X6.3 on February 22, 2024. It is also the 11th<\/sup> X-class flare since X1.3 on May 5, 2024.<\/p>\n A Type IV and II radio emissions (estimated velocity of 564 km\/s), were associated with the flare event, suggesting a strong coronal mass ejection (CME) was produced.<\/p>\n Additionally, a 10cm Radio Burst (tenflare) lasting 23 minutes and with a peak flux of 800 sfu was associated with this event, indicating that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. The noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.<\/p>\n Radio frequencies were forecast to be most degraded over east Asia, Australia, New Zealand, and the Pacific Ocean all the way to Alaska, U.S. and Canada at the time of the flare.<\/p>\n![\"YouTube](\"https:\/\/i.ytimg.com\/vi\/vMY8SaKvzcA\/hqdefault.jpg\")
