The term "kill shot" is a reference to a "remote viewer" who shall remain un-named...kind of a sick joke, pardon me.
Yes, there may be serious consequences to one or more of these extreme CME events. Not NASA, not NOAA, or anyone can really predict what will happen until it happens. Please re-read the posts from the last 3 or 4 pages carefully. I have shown that in 2008, scientific experts couldn't even agree on the DEFINITION of what a CME was! They are only guessing and "stabbing-in-the-dark" with their predictions. They may be 2% more accurate than a guy w/ a dart-board, but they make a helluva lot more money (thanx to the suckerz, the taxpayerz).
I guarantee that I've worked harder today to get a grip on what's happening with the Sun & geo-space than any one person with NASA or NOAA, and probably the Geospatial Intelligence Agency & the Air Force Weather Squadron. I'm not bragging...I wish I got paid , but I do it out of LOVE.
A sub-storm, like in 1989, flashed-up within a ten-minute (or less) surge of geo-magnetically-induced current energy. There's no way to predict exactly where or when the weak link in the grid will fail. There's a hundred unpredictable variables, we can only shut stuff down to be cautious, and that costs money. So they plan to make every dollar until shit fails catastrophically.

I think the underestimated threat of a major geomagnetic storm is the satellite infrastructure. Not just losing GPS or ATMs for a day or two; but what if one or more satellites lose their orientation, orbital path, communication, or power source due to excessive charging or radiation exposure. One failed satellite,off of its course, could lead to a cascade of colliding satellites; each collision spraying 1000's of pieces of shrapnel to destroy other space assets. Near-Earth orbit could be rendered uninhabitable for generations.
