Solar flares happen when magnetic-field loops threading through sunspots get twisted and break, producing massive amounts of radiation that accelerate charged particles into space. The largest one that Sol ever produced in recorded history was on September 1st, 1859, and it was observed by the British astronomer Richard Carrington. Hours later, auroras were seen in tropical latitudes and telegraph lines threw off sparks, even when disconnected from their batteries.
