SS: that small machholz sungrazer caused a big geomagnetic storm on the earth auroras to northern us .. i think that geomagnetic activity in the magnetosphere causes earth core heating .. the earth’s magnetic field is generated by the earth’s core .. and also i think the auroras generate away from the poles because¬† there is something called polar vortexes which seem to exist at the poles of active planets and moons like saturn and titan where these polar vortexes have been seen .. we have detected auroras at the north pole of jupiter too .. we will have to see how the earth reacts to a full x-flare if it causes earth core heating and magma expansion .. if we were to go by my archives and polestar sciences then that is what has happened .
