although the concern is more about geomagnetic effects on the power 
grid, anything that helps understand  the relationship between the 
sun and the geomagnetic field is a good thing.   This particularly 
caught my eye:

Obviously Grayland would be a fine site for a geomagnetic observatory....

best wishes,

Nick
