Carrington Event
The Carrington Event was the most intense geomagnetic storm in recorded history, peaking from 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally[1] and caused sparking and even fires in multiple telegraph stations.
The aurora borealis over the Rocky Mountains in the United States was so bright that the glow woke gold miners, who allegedly began to prepare breakfast because they thought it was morning. The conversation was carried on for around two hours using no battery power at all and working solely with the current induced by the aurora, the first time on record that more than a word or two was transmitted in such manner.
