During the past 24 hours, aurora displays have descended as far south as Wisconsin, Minnesota, and Michigan in the United States. Earth’s magnetic field is still reverberating from a CME strike on March 10th.
Solar wind conditions favor more geomagnetic storming in the hours ahead. A solar wind stream flowing from the indicated coronal hole is likely to brush past Earth’s magnetic field on or about March 14th.
