The Aurora is cause when charged particles from the sun, called solar wind, hit the earth’s manetosphere,
creating a gigantic electro-magnetic generation of energy.
Photographing them last night was interesting to me as I had some foreground subjects with the trees, and because it spanned from mountain to city scape
Auroral activity is forecast to increase the next couple days so I am getting ready for it
(and trying to get some sleep too).
