The Aurora Borealis, also known as the Northern Lights, made a very rare appearance over parts of North Dakota last night (Jun 23). Normally, the Northern Lights are seen during the winter, and very seldom this far south. They may be visible again tonight (Jun 24), though expected cloud cover might interfere a bit. - Bismarck/Minot/Williston/Dickinson-KXNEWS,ND
