Still Waters Posted January 29, 2020 #1 Share Posted January 29, 2020 A new form of the northern lights has been captured by amateur enthusiasts, researchers have revealed. The phenomenon of glowing green lights rippling across the night sky, also known as the aurora borealis, have long captivated the public and experts alike. The northern lights have been seen in many forms, including “quiet arcs”, spirals and corona. But now, thanks to the work of amateur enthusiasts, Palmroth and colleagues say they have discovered a previously unknown form, a pattern they claim resembles sand dunes. https://www.theguardian.com/science/2020/jan/29/amateur-stargazers-capture-new-form-of-northern-lights 3 1 1 Link to comment Share on other sites More sharing options...
L.A.T.1961 Posted January 29, 2020 #2 Share Posted January 29, 2020 It looks a lot like a gravity wave formation, maybe a noctilucent cloud formation illuminated by the aurora instead of the sun ? https://www.spaceweather.com/archive.php?view=1&day=16&month=08&year=2018 1 Link to comment Share on other sites More sharing options...
