The history of communication satellites is however extremely brief. It
would be unfortunate if it coincided with an unusually benign period of
solar activity!

The "perfect solar storm" of 1859 was powerful enough to disrupt the
cutting edge communications technology of the day - the electric
telegraph. Power surges in telegraph wires caused widespread fires in
both Europe and the United States.

I wonder what effect an event of this magnitude (or worse) would have on
today's communications infrastructure?
