On Nov. 11, the aurora was seen dancing across the night sky across the U.S. after solar flares and CMEs on the Earth-facing disk of the sun. The Northern Lights were even reported as far south as Florida. An entire rotation later, that same active region on the sun is again facing Earth \u2014 meaning that whatever solar flares and CMEs produced are likely to mean a high chance of aurora during mid-December this year.<\/p>\n<p>This week&#8217;s display has its roots in an M8-class solar flare on Dec. 6, which unleashed a CME that is now heading straight for Earth.<\/p>\n<p>An X1.1 class solar flare exploded on the sun on Dec. 8, making Dec. 10-11 a date to circle in the diary as a potentially even stronger geomagnetic storm.<\/p>\n<p><a class=\"embed-base color-body color-body-border link-embed embed-3\" href=\"https:\/\/www.forbes.com\/sites\/jamiecartereurope\/2025\/11\/06\/how-to-take-great-northern-lights-photos-with-a-phone---by-an-expert\/\" target=\"_blank\" aria-label=\"How To Take Great Northern Lights Photos With A Phone \u2014 By An Expert\" data-ga-track=\"forbesEmbedly:https:\/\/www.forbes.com\/sites\/jamiecartereurope\/2025\/11\/06\/how-to-take-great-northern-lights-photos-with-a-phone---by-an-expert\/\" rel=\"nofollow noopener\">ForbesHow To Take Great Northern Lights Photos With A Phone \u2014 By An ExpertBy Jamie Carter<\/a>Where And When To See The Northern Lights<\/p>\n<p>NOAA&#8217;s forecast has a G3 geomagnetic storm estimated to develop between 6:00-9:00 UTC (1:00-4:00 a.m. EST) on Tuesday, Dec. 9.

In this region, auroras are nightly (though clear skies are not!), giving you a much better chance. The best places to see the aurora include Alaska, northern Canada, northern Norway, Sweden, Finland, and Iceland. In these latitudes, auroras are visible several nights per week from September through March, with those two months giving you the best chances.<\/p>\n<p>Wishing you clear skies and wide eyes.<\/p>\n","protected":false},"excerpt":{"rendered":"The aurora dances across the night sky over Princeton, Minnesota, United States, on November 11, 2025.
