During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae as far south as the Canary Islands off Africa, the Florida Keys in the United States, and the Yucatán Peninsula in Mexico. On the other side of the world, the Aurora australis was seen in Queensland, Australia, Namibia and southern Brazil, among many other places.
