Second CME to Hit Earth's Magnetic Field

Another great image from the Solar Dynamics Observatory (SDO) of the news-making solar event on August 1, 2010 resulting in two Coronal Mass Ejections (CMEs) launched in Earth's direction.

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-energize the fading geomagnetic storm and spark a new round of Northern Lights.
