I remember a solar storm hit years ago and popped breakers and melted power lines in Canada and up north that way in New York. power was out for a while from news reports I saw.
ive yet to see a statement by an experts saying what side of the planet will take the brunt of it, maybe it will be the whole planet, I guess we will see. but what I did see a couple experts saying that they expect it to be a 5 on a scale of five in intensity. I once saw a show about the satellite nasa created to monitor these solar storms so that communication and military satellites can be turned off as the energized particles pass by so the satellites won't get fried.
just in case ive got my old trusty Lincoln ranger with 8000 watt 120/240v all tuned up with new oil and air filter and non ethanol gas ready if its needed. and at least 20 gallons of gas to try and keep the freezer frozen just in case the power lines melt.
