Where should I shoot a solar flare that is at least as strong as [the solar flare(s) in 2012](http://science.nasa.gov/science-news/science-at-nasa/2014/23jul_superstorm/) for the most death? What else would happen? And how much death, in percentage of world population, would the solar flare cause?

That can also include the preceding flares that ""plowed the road" for the superstorm."

Yes, I know about [Solar flares: “the week the earth stood still”"](https://worldbuilding.stackexchange.com/questions/6713/solar-flares-the-week-the-earth-stood-still)

Scientifically Possible, and possibly believable, please.

You can also include reactions to the Event as part of loss of life...

I know that I can't get vaporized bodies or spontaneous combustion via solar phenomena. 

I suppose falling satellites and failing nuclear plants could do a lot of damage?

Okay, now we have an answer that could lead to total biosphere destruction... useful.

What if I didn't want anything other than solar flares and their after-effects?
