Geomagnetic Storm

  1. Nov 14, 2012 #1
    Hi all,
    I have a question regarding geomagnetic storms:
    --why always they affects the Northern Hemisphere?
    Or did i got this idea wrongly?

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

    yup you did :wink:
    but thats OK you have come to a good place of learning :smile:

    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 ?
