Geomagnetic activity intensifies: auroras may light up American skies<\/strong><\/p>\n Tonight, Saturday, May 31<\/strong>, and through the weekend, the northern lights could glow above a wide swath of the United States<\/strong>, painting the sky in shimmering shades of green and purple. The National Oceanic and Atmospheric Administration (NOAA)<\/strong> has forecast increased geomagnetic activity<\/strong>, meaning a rare opportunity for skywatchers far beyond the Arctic Circle to witness this breathtaking phenomenon.<\/p>\n Earth is currently under the influence of high-speed solar wind<\/strong>, which is pressuring the planet\u2019s magnetic field<\/strong>, triggering minor G1 geomagnetic storm conditions<\/strong> \u2014 though stronger activity isn’t off the table. Just a few days ago, a surprise G3 storm on May 28<\/strong> sparked auroras as far south as Italy and 17 U.S. states<\/strong>, despite initial forecasts predicting only mild activity.<\/p>\n This weekend, forecasters at NOAA\u2019s Space Weather Prediction Center<\/strong> anticipate the Kp index to peak at 4.67<\/strong>. That\u2019s strong enough to push the auroral oval<\/strong> farther south, meaning that some mid-latitude states may catch a glimpse of the northern lights<\/strong> \u2014 conditions permitting.<\/p>\n According to NOAA\u2019s latest aurora forecast<\/strong>, here are the 15 U.S. states most likely to witness auroral activity<\/strong>, ranked from most to least favorable based on location relative to the auroral oval:<\/p>\n Alaska<\/strong>, Montana<\/strong>, North Dakota<\/strong>, Minnesota<\/strong>, Upper Michigan<\/strong>, Wisconsin<\/strong>, Idaho<\/strong>, Vermont<\/strong>, Maine<\/strong>, New Hampshire<\/strong>, New York<\/strong>, South Dakota<\/strong>, Wyoming<\/strong>, Washington<\/strong>, and Iowa<\/strong>.<\/p>\n If the geomagnetic activity unexpectedly escalates to G3 levels<\/strong>, auroras could stretch even farther south<\/strong> \u2014 possibly illuminating skies in Illinois<\/strong> or Oregon<\/strong>.<\/p>\n For the best chance to see the northern lights<\/strong>, head to a dark, north-facing location far from urban light pollution<\/strong>. As summer solstice (June 20\u201321)<\/strong> approaches, the night sky grows shorter<\/strong>, so 1\u20132 a.m. local time<\/strong> may be your best window.<\/p>\n Conditions are ever-changing.
