The aurora is not a screen saver

A cold-night argument for treating the northern sky as infrastructure, not spectacle.

I spent fourteen January nights outside Dawson City with a battery pack in my coat and a notebook going stiff in the frost. The green arrived after midnight, not as a curtain at first, but as a pressure change: the whole ridge seemed to inhale before the sky opened.

Light with a working altitude

Calling it magic lets us keep it distant. The better story is sharper: oxygen atoms, struck high above the weather, returning energy as a cold green line that can make a riverbank visible without a lamp. That knowledge does not flatten the experience; it gives the glow a body and a height.

The towns that live under this weather already know the difference. A forecast can change a winter drive, a school night, a power inspection, or the route of a late snowmachine. Beauty is only the most exportable part of the system.
