What Kp 9 means tonight
Kp 9 is the maximum level of the geomagnetic activity scale - a G5 extreme storm. At this level the aurora can be visible from almost anywhere in the world with dark skies, including locations in the southern hemisphere that never normally see aurora. The G5 storm of May 2024 was the strongest in 20 years and produced aurora visible from as far south as Mexico, Florida, Spain, and New Zealand's North Island. These events are rare - perhaps once per solar cycle - but when they arrive they are extraordinary.
