>You CAN'T predict massive Solar Flares that far in advance. At best, you get a 30-seconds sat heads-up.
IDK exactly what you're talking about… we can see solar flares erupt in real time, and it generally takes 3-5 DAYS for the ejected mass to strike our magnetosphere. as for a direct blast of EM radiation that arrives at the same time as we see the flare, there are NO solar flares powerful enough to damage the grid so there is no need to concern ourselves with that.
