The Carrington event was a big one. It is estimated to have been an X40 flare. This article is about an X1.1 flare. Telegraph poles caught fire. The auroras were so bright people woke up and started making breakfast even though it was the middle of the night. They were visible as far south as central Mexico! If we got hit by a Carrington scale flare today we would be repairing the power grid for the next half century.
