Silly. It is most likely something to do with atributes of the magnetosphere at the poles; just as why you don’t get “northern lights” except at the poles.
I’ve observed “northern lights” as far south as Des Moines, IA...
The earth’s protective magnetic shield is weakening in advance of an anticipated flip in polarity. True magnetic north is skeedaddling across the top of the globe and veering headlong into Russia, forcing NOAA to accelerate its update schedule in order to permit navigation equipment manufacturers and users to avoid excessively large errors. Simultaneously our Sun is in the midst of the deepest solar minimum (in terms of the 11 year sunspot cycle) of the space age and is apparently also entering a multi-cycle grand solar minimum. The confluence of these factors is apparently allowing the solar wind to rush relatively undeflected toward and into the earth’s polar regions. In other words, this actually is quite out of the ordinary.
