The Suspicious Observers youtube channel is a good place to start seeing stuff about the galactic current sheet and geomagnetic excursions... he presents a credible interpretation of the data of solar flare activity over the last 170 years since the Carrington Event in 1859 fits an exponential decay curve heading towards a field reversal sometime in the next 30 years

it will mean a lot of really bad storms like Helene and increased rainfall, more seismic and volcanic activity, increased radiation reaching the earth, more auroras further from the poles from solar activity far less than ever caused this much in recorded history
