People as far south as Ohio and Indiana may be able to see the northern lights Wednesday night (Sept. 6), thanks to a powerful sun storm.
On Monday (Sept. 4), the sun blasted out a huge cloud of superheated plasma known as a coronal mass ejection (CME). This fast-moving CME is expected to slam into Earth overnight Wednesday, triggering strong geomagnetic storms.
Such storms often supercharge Earth's auroras, the ghostly displays of dancing color also known as the northern and southern lights. And that could be the case Wednesday night through early Thursday morning (Sept. 7): Auroras are likely to extend southward into the continental United States, from Washington and Idaho in the West to Indiana and Ohio in the Midwest and New England in the Northeast, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC).
