Auroras and Geomagnetic Storms

The Auroras are not just some light show that clouds over us at either poles of the earth. They are solar winds that show highly charged electrons interacting with particles in the earth's atmosphere. When these solar winds leave the sun, they find lines of magnetic force generated by earth's core, and flow through the magnetosphere.

Auroras can be a few different colors, but their color depends on the concentrations of gases in te atmosphere, and at what altitude these concentrations are found.


Fox News reporter, Dan Amarante, reported that a geomagnetic storm lead by solar flares was underway late last Sunday (March 15) when a Coronal Mass Ejection was released from the sun with highly charged electron particles. Geomagnetic storms occur when there is a disturbance in  the earth's magnetosphere caused by solar winds shock waves, such as these, and/or a clouding/interaction with the earth's magnetic field. These storms were able to be seen in Connecticut Sunday night and these normally occurs at either of the earth's poles.

Should we be concerned we were able to see these in Connecticut do the geomagnetic storm?

What does this say (if anything) about our sun? Is it dying? Should we study this phenomenon more?
