Astro-Calendar: Sep. / 160th Anniv: Carrington Event Solar Mega-Storm

                 
Drawing, by English Amateur Astronomer Richard C. Carrington, of sunspots on the Sun on 1859 September 1, which led to the major Solar Storm of 1859 better known as the Carrington Event. This was one of the first known geomagnetic storms to have major affects on Earth's magnetic field, 1859 September 1 to 2, including great auroral displays (even as far south as Cuba, people could read a newspaper by the bright glow) and caused severe electrical disruptions, electrifying telegraph systems and shocking telegraph operators and technicians (some telegraph systems actually caught fire). Mr. Carrington observed a Solar Flare (the first such observation in history), which is associated with a major, billion-ton Coronal Mass Ejection (CME) which caused the Carrington Event, just before 12:00 Noon on 1859 September 1. Such a solar storm today could bring down electrical grids (which did happen in Quebec in March of 1989), severely disrupt radio communications, destroy the electronics in satellites, and according to a NASA-funded study by the National Academy of Sciences such a storm could cause a trillion dollars in damage to the nation's electronic systems requiring years for recovery. In fact, a Carrington-Class Solar Mega-Storm did occur on the Sun on 2012 July 23, although in this case the CME missed the Earth.
