>Can anyone explain why I should care about Schumann Resonance? What is it even depicting? Where is it measured? Isn't it affected by electrical storms? It's basically a magnetic storm chart right?
it's a slide post
the poster never explains why it is relevant here
and yes, the chart is interesting but as you've said, it's basically just charting the secondary effects of the solar output's effect on the Earth's magnetic field
it's a fascinating phenomena but has no place here
