Red indicates positive magnetic polarity, like a magnetic has 1 negative and positive pole, Off the charts is self explanatory one would think, and you've just shown graphically why we are having power grid failures, for exactly the reasons I predicted. i WOULD NOT trust the proton flux density diagram that shows the earth and circular representations of proton flux, it's faked. On places protons in the magnetosphere and from the cloud are touching the surface and this diagram indicates otherwise. Also the two distinct levels of proton flux being such a distinct circle are unlikely to be real, it would be a more gradual transition and not circular. Really
