Carrington event was a giant cormorant (Jk, staying with the evolving misspelling) mass ejection that lit up telegraph wires and devices and started fires from wire fences sparking. Aurora all the way to equator. Was in 1859. Would probably benchmark “sucks” if it happened today...
ThankQ ! Not being the scientific kind of person, that sounds pretty amazing. Think I need to do some reading up on it (and use a handy dictionary at the same time.)
