The Carrington Event of 1859 took place over the 1st and 2nd of September in that year. The effects lasted more than two days. A flare erupted from the Sun, and sped towards Earth at an abnormally high speed. When it arrived it caused auroras far closer to the equator than fit the status quo — at least as close as the country of Columbia. The pretty lights were pleasant, but the accompanying magnetic fist on the face of the planet was not. The only electrical systems in existence were telegraph lines, but that was enough. Two continents had a significant portion of their communication setups destroyed in a matter of hours.
