Columbia, TN's night sky, measured from orbit

Columbia reads as suburban edge on this dataset's scale. A noticeable glow near the horizon. Brighter stars and constellations are easy to pick out; the Milky Way is washed out. That's brighter than 15.7% of the 3,206 US cities in this dataset.

Note the source: a satellite reading of upward light, not a visual Bortle scale reading. The two measure related but different things.
