| This is by no means an exhaustive list of cities. It has most capitol cities, and extreme north/south cities for "tall" countries like the US, Canada, Russia, China, Chile, and Argentina. Numbers cribbed from Wikipedia. Just because the server sky orbit is briefly above the horizon at a far north latitude does not mean access is practical. Orbits go from southern horizon to southern horizon, and it is elevation that matters, especially at night when the arrays that are due south may be eclipsed and in darkness. |

Cities
This is by no means an exhaustive list of cities. It has most capitol cities, and extreme north/south cities for "tall" countries like the US, Canada, Russia, China, Chile, and Argentina. Numbers cribbed from Wikipedia.
Just because the server sky orbit is briefly above the horizon at a far north latitude does not mean access is practical. Orbits go from southern horizon to southern horizon, and it is elevation that matters, especially at night when the arrays that are due south may be eclipsed and in darkness.
