The Northern Lights<\/a> may be visible in northern skies from 10 northern U.S. states and Canada this Thanksgiving. <\/p>\n According to a forecast<\/a> from the National Oceanic and Atmospheric Administration\u2019s Space Weather Prediction Center, a G1-rated geomagnetic storm may be ongoing as it gets dark, with northeastern states best placed. <\/p>\n It comes in the wake not of a solar flare or a coronal mass ejection, but high solar wind speeds. It means an increased chance of aurora at high latitudes. <\/p>\n Northern Lights Forecast: What To Expect<\/p>\n The latest forecast calls for a G1 geomagnetic storm after dark in North America on Thursday, Nov. 27. <\/p>\n NOAA predicts<\/a> that “chances for isolated An almost 50%-lit waxing gibbous moon will be visible in the south, with Saturn close by in the southeast. A closer conjunction of the moon and Saturn<\/a> will occur over the next few nights. <\/p>\n NOAA’s aurora viewline forecast for Nov. 27, 2025. <\/p>\n NOAANorthern Lights Forecast: Where And When<\/p>\n NOAA\u2019s latest aurora viewlines<\/a> indicate that aurora displays are a possibility in northern U.S. states and Canada, with 10 U.S. states having a chance after dark on Thanksgiving night.<\/p>\n U.S. states that may see aurora include Alaska, Washington, Idaho, Montana, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan and Maine. <\/p>\n Since this may be a photographic aurora (see below), for the best views, locate a dark place using the Dark Sky Place Finder<\/a> and a light pollution map<\/a>. The darker the northern sky, the more vibrant the display \u2014 even during moderate geomagnetic storms. A clear northern sky will be required. <\/p>\n Northern Lights Forecast: Latest Updates<\/p>\n To check visibility in real time, use NOAA\u2019s 30-minute aurora forecast<\/a>, or download apps such as Aurora Now, My Aurora Forecast or Glendale Aurora for up-to-the-minute alerts and live solar wind data.<\/p>\n Aurora-chasers frequently use the Kp index to predict the intensity of a geomagnetic storm, but for aurora displays, the interplanetary magnetic field\u2019s Bz component is more important. Data on Bz can be found in some of the above apps and on SpaceWeatherLive.com<\/a>. <\/p>\n Bz determines how easily solar energy enters Earth\u2019s magnetosphere. When Bz points north, Earth\u2019s field resists it; when Bz swings south, the two fields connect, allowing plasma to stream in. A sustained southward Bz of \u22125 nT or stronger usually signals an imminent display of aurora.<\/p>\n
\nperiods of G1 (Minor) geomagnetic storming levels remain possible
\nthrough 27 Nov.” <\/p>\n
