AURORAS IN THE USA: A coronal mass ejection (CME) hit Earth's magnetic field on March 10th. The impact set off a G1-class geomagnetic storm and sent Northern Lights rippling over the US-Canadian border into states such as Wisconsin, Minnesota, and Michigan. Sky watchers who hadn't seen auroras in years captured beautiful photos of green and purple streamers. This is another sign that Solar Cycle 24 is heating up.
