The CME is expected to impact Earth on September 10, potentially triggering a G2 \u2013 Moderate geomagnetic storm. Concurrently, heightened activity near the Sun\u2019s west limb has caused a sharp increase in proton levels, resulting in an S1 \u2013 Minor solar radiation storm at 08:50 UTC today.<\/strong><\/p>\n<p>The CME was first observed in ESA\/NASA LASCO C2 coronagraph imagery at approximately 01:36 UTC. Analysis and modeling of the CME suggests arrival to Earth by mid to late Tuesday, September 10.<\/p>\n<p>G2 \u2013 Moderate geomagnetic storming is likely on September 10. Elevated activity is likely to persist into September 11, keeping G1 \u2013 Minor geomagnetic storm conditions likely throughout the first half of the day.<\/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=\"Filament eruption produced Earth-directed CME - September 8, 2024\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/LMxBXogbPsY?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<p>A G2 \u2013 Moderate geomagnetic storm can have several significant effects, particularly in high-latitude regions. <\/p>\n<p>Power systems in these areas may experience voltage alarms, and prolonged storms can lead to transformer damage.

Additionally, auroras, typically visible in regions around 55\u00b0 geomagnetic latitude, have been observed as far south as New York and Idaho during such storms.<\/p>\n<figure class=\"wp-block-image size-full\"><figcaption class=\"wp-element-caption\">Image credit: ESA\/NASA LASCO C2<\/figcaption><\/figure>\n<p>Meanwhile, following recent activity near the Sun\u2019s west limb, proton levels began increasing at 06:00 UTC on September 9, reaching the S1 \u2013 Minor solar radiation storm threshold by 08:50 UTC.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"475\" src=\"https:\/\/watchers.news\/wp-content\/uploads\/2024\/09\/drap-0932utc-september-9-2024.webp\" alt=\"drap 0932utc september 9 2024\" class=\"wp-image-188480\" srcset=\"https:\/\/watchers.news\/wp-content\/uploads\/2024\/09\/drap-0932utc-september-9-2024.webp 850w, https:\/\/watchers.news\/wp-content\/uploads\/2024\/09\/drap-0932utc-september-9-2024-300x168.webp 300w, https:\/\/watchers.news\/wp-content\/uploads\/2024\/09\/drap-0932utc-september-9-2024-768x429.webp 768w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\"\/><\/figure>\n<\/div>\n<p>An S1 \u2013 Minor solar radiation storm has limited effects and poses no risks to biological systems or satellite operations.
