"Rare Severe Geomagnetic Storm Brings Northern Lights to Unusual Locations"

A severe geomagnetic storm hit the Northern Hemisphere on Sunday night, causing beautiful aurora borealis sightings but also disrupting navigation systems, satellites, and power grids. The National Oceanic and Atmospheric Administration predicted that the northern lights could be visible in Northern California, but cloudy conditions on the West Coast obscured the rare sightings from view. The storm caused disturbances in Earth's magnetic field, doubling the k-index value and potentially causing power grid fluctuations and increased drag on low orbiting satellites. The worst impacts were felt overnight by people living at above 50 degrees latitude, which falls in northern Canada.
