ALASKA, UNITED STATES – SEPTEMBER 30: Intense northern lights (aurora borealis) above Kp5 were observed in Alaska’s Matanuska-Susitna Borough, around Chickaloon and Bonnie Lake, on the night of September 30 to October 01, 2025. The aurora created a breathtaking scene, illuminating the snow-capped peaks of the mountains surrounding the Matanuska Valley and their reflections on Bonnie Lake.

The Northern Lights <\/a>may be visible in the U.S. this weekend, according to a forecast by the National Oceanic and Atmospheric Administration\u2019s Space Weather Prediction Center<\/a>. <\/p>\n Sky-watchers in 12 U.S. states may have a chance to see the aurora borealis on the northern horizon as soon as it gets dark. <\/p>\n Although the agency\u2019s three-day forecast<\/a> does not indicate a geomagnetic storm, there have been heightened levels of geomagnetic activity all week as Earth moves through a high-speed stream of solar wind. <\/p>\n ForbesNorthern Lights Alert: Sudden Auroras In U.S. May Persist This WeekBy Jamie Carter<\/a>Last Chance For \u2018Equinox Auroras\u2019<\/p>\n It\u2019s been a busy week<\/a> for the Northern Lights. \u201cThese are the last gasps of an occasionally strong 5-day geomagnetic storm that produced magnificent auroras around the Arctic Circle and about a dozen US states between Sept. 28th and Oct. 2nd,\u201d according to Spaceweather.com<\/a>. <\/p>\n According to NOAA\u2019s forecast, the Kp index \u2014 which provides a rough guide to the intensity of aurora displays \u2014 may reach 4. According to NOAA<\/a>, expect \u201cprimarily unsettled to active conditions persisting through 05 Oct.\u201d<\/p>\n The root cause<\/a> of all; of this unpredicted activity? Autumn equinox<\/a> on Sept. 22. The Northern Lights occur when charged particles from the sun accelerate down Earth\u2019s magnetic field lines and collide with molecules high in Earth\u2019s atmosphere. However, it\u2019s magnetism that makes it all work \u2014 and it changes dramatically around the equinoxes in March and September. <\/p>\n NOAA’s aurora viewline for Friday, October 3, 2025. <\/p>\n NOAAWhere The Northern Lights May Be Visible<\/p>\n NOAA\u2019s latest aurora viewlines<\/a> indicate that aurora displays are a possibility in northern U.S. states and Canada, with 12 U.S. states having a chance after dark on Friday, Oct. 3 and potentially through the weekend \u2014 though the imminent full harvest moon<\/a> may make the aurora slightly harder to see.<\/p>\n U.S. states that may see aurora include Alaska and (northerly parts of) Washington, Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, New York and Maine. Dark northern skies away from urban light pollution are likely to offer the best views. <\/p>\n ForbesNorthern Lights Alert: Why Aurora Could Now Suddenly SpikeBy Jamie Carter<\/a>What Is An \u2018Equinox Aurora?\u2019<\/p>\n Geomagnetic storms can become particularly intense in the weeks surrounding the equinox because the magnetic field of Earth and the solar wind align. The phenomenon is known as the \u201cRussell-McPherron Effect\u201d as per a paper<\/a> in 1973. <\/p>\n The sun and Earth\u2019s magnetic fields are lined up with their equators, but since Earth rotates on a tilted axis, they are not aligned. Twice a year, near the equinoxes, the south-pointing part of the sun\u2019s magnetic field more easily connects with Earth\u2019s magnetic field. When that happens, charged particles from the sun penetrate Earth\u2019s defenses more easily, driving more (and more intense) geomagnetic storms and auroras.<\/p>\n Latest Aurora Forecast Tonight<\/p>\n Check NOAA\u2019s 30-minute forecast<\/a> or use the Glendale Aurora and My Aurora Forecast apps. Although the Kp index is important \u2014 as is whether a geomagnetic storm commences \u2014 what\u2019s typically decisive in the formation of aurora is the direction of the interplanetary magnetic field (Bz). It\u2019s only when the Bz is south that active auroras are seen. Data about the Bz direction can be seen easily on websites like SpaceWeatherLive.com<\/a> and Aurora Forecast<\/a>. <\/p>\n Wishing you clear skies and wide eyes.<\/p>\n","protected":false},"excerpt":{"rendered":"ALASKA, UNITED STATES – SEPTEMBER 30: Intense northern lights (aurora borealis) above Kp5 were observed in Alaska’s Matanuska-Susitna…\n","protected":false},"author":2,"featured_media":192019,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[15386,4943,15385,15387,49,48,4942,15383,15382,91429,15384,91430,66,306],"class_list":{"0":"post-192018","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-aurora-alert","9":"tag-aurora-borealis","10":"tag-aurora-forecast","11":"tag-aurora-tonight","12":"tag-ca","13":"tag-canada","14":"tag-northern-lights","15":"tag-northern-lights-alert","16":"tag-northern-lights-forecast","17":"tag-northern-lights-new-york","18":"tag-northern-lights-tonight","19":"tag-northern-lights-when-where","20":"tag-science","21":"tag-space"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/192018","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=192018"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/192018\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/192019"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=192018"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=192018"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=192018"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
