Geomagnetic Storms: Why Affect Northern Hemisphere?

[sailorimc]

Hi all,
I have a question regarding geomagnetic storms:
--why always they affects the Northern Hemisphere?
Or did i got this idea wrongly?
Thanks

They are most noticeable at the poles [both poles], since that is where Earth's magnetic field originates.

yup you did
but that's OK you have come to a good place of learning

it has been seen by orbiting satellite photographs over the years that aurora activity at the North and South Poles ( caused by geomagnetic storming)
can often be an almost mirror image of each other.

I used to live in southern New Zealand and from a young age viewed and photographed many aurora
have a look here for some of my pics

just out of curiosity, where did you get the idea that they only affect the northern hemisphere ?
something you read or heard ?

cheers
