NOAA predicts auroras could be seen as far as Oregon, Pennsylvania and even Iowa from Wednesday to Friday.
FILE - The aurora borealis appears in the sky on Jan. 8, 2017, near Ester Dome mountain about 10 miles west of Fairbanks, Alaska.
The storm was originally predicted to be no stronger than a category G2 but since the sun ejected multiple CMEs, at least four of those could have direct contact with Earth, upping the category to a G3, During this cycle, large eruptions of immense energy containing the power of several nuclear bombs explode from the surface of the sun, ripple through space and inevitably strike Earth. These are CMEs. Traveling at over a million miles per hour, the ejected mass of protons and electrons can cross the 93-million-mile distance from the sun to the Earth in a matter of days.
But every now and then, this massive explosion of energy does hit our planet, resulting in a geomagnetic storm which usually manifests into auroral lights typically seen near the north and south poles.
