NOVA last week was on the sun and predominantly about sun spots, CME's,
etc. Per the sun forecasters an event such as 1859 is not an "if" but a
"when".

The main fear they have is that electric transformers world wide would
be destroyed. Electric co's do not have replacements lying around and
the larger transformers would take years to replace across a large system.

Hmm, interesting.
I'm also worried about satellites getting fried... especially navstar

It would take a storm 1/10th power to temporarily or permanently affect
satellite nav systems temporarily to permanently.

If the electrical grid is as damaged as could be, satellite will be the
least of your worries.
