The event started at 21:58 and ended at 22:29 UTC.<\/p>\n<p>Associated with this event was a Type II Radio Emission with an estimated velocity of 1 246 km\/s, indicating a coronal mass ejection (CME) was associated with the flare event.<\/p>\n<p>Additionally, a 10cm Radio Burst (tenflare) lasting 9 minutes and with a peak flux of 810 sfu was registered from 22:09 to 22:18 UTC. A 10cm radio burst indicates 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. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><\/figure>\n<\/div>\n<p>Radio signatures were forecast to be most degraded over the Pacific Ocean at the time of the flare.<\/p>\n<p>Coronagraph imagery is still not available to confirm whether we have an incoming CME. However, this region is within the Earth-strike zone \u2014 meaning any CME produced by it will likely have an Earth-directed component.<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<p>\n<iframe loading=\"lazy\" title=\"Major X7.1 solar flare erupts from AR3842 - October 1, 2024\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/_JvC3AWEIws?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/p>\n<\/figure>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"966\" height=\"842\" src=\"https:\/\/watchers.news\/wp-content\/uploads\/2024\/10\/X7.1-solar-flare-october-1-2024-sdo-aia-131.webp\" alt=\"X7.1 solar flare october 1 2024 sdo aia 131\" class=\"wp-image-205423\" srcset=\"https:\/\/watchers.news\/wp-content\/uploads\/2024\/10\/X7.1-solar-flare-october-1-2024-sdo-aia-131.webp 966w, https:\/\/watchers.news\/wp-content\/uploads\/2024\/10\/X7.1-solar-flare-october-1-2024-sdo-aia-131-300x261.webp 300w, https:\/\/watchers.news\/wp-content\/uploads\/2024\/10\/X7.1-solar-flare-october-1-2024-sdo-aia-131-768x669.webp 768w\" sizes=\"auto, (max-width: 966px) 100vw, 966px\"\/><figcaption class=\"wp-element-caption\">X7.1 solar flare on October 1, 2024.
