Second CME to Hit Earth's Magnetic Field Today

Earth's magnetic field is still reverberating from the CME impact of August 3rd, which sparked auroras as far south as Wisconsin and Iowa in the United States. Analysts believe a second CME is right behind it, due to arrive today. This second impact could re-energise the fading geomagnetic storm and spark a new round of Northern Lights.
