It is a large geomagnetic storm and over a hundred and fifty years ago, it set telegraph stations alight. Obviously at that time in history, there wasn't a lot of electronics about, but if it were to happen again, what happens to all that we rely on when those transformers fry in the radiation?
Probably then I will get the old battery-powered radio out of the attic and live for a while like my grandfathers did in the first half of the 20th century.
I am not sure that would even work :D
