We know the sun reverses its magnetic field every 11 years or so in line with a solar cycle that might be influenced by the larger gas giants like jupiter.
So although the jupiter/sun link is tenuous or at best still being determined, I wonder what if any astronomic influences would impact the reversal of earths magnetic field?
Furthermore the suns field reversal is accompanied by a period of increased activity, such as solar flares etc, I wonder what the earthly equivalent will be?
Hi Jules, Interesting ... (i didn't see your post until now) i thought the actual flip in polarity happened quickly, But, apparently not? I thought the Geomagnetic record was a record of N-S reversals ... with no easts or wests recorded... ?¿? ... crustal folding and whatnot must complicate reading the record?
