A geomagnetic storm is in progress as Earth’s magnetic field is hit by the effects of recent strong solar activity. Sky gazers in Scandinavia, Canada, Alaska and northern-tier US states from Maine to Washington may see spectacular auroras after nightfall. The hours around local midnight are usually best for aurora watching.
On July 14-15 Northern Lights could be seen in the United States as far south as California, Colorado, Missouri, Utah, Wisconsin, Iowa, Minnesota, Washington, Illinois, Kansas, Nebraska, Michigan and Arkansas.
Meanwhile in the southern hemisphere, the aurora australis has been sighted in New Zealand, Australia, and directly above the South Pole itself.
