Anderson, SC Night Sky Brightness
Anderson, SC: how dark is the sky here?
Anderson 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. Anderson's sky is brighter than 32.8% of the 3,206 cities in this dataset.
This comes from a satellite measuring light radiating upward, not a person's eyes on the ground, so it isn't the same as a Bortle class, though the two track each other closely - see the Bortle scale guide for where they can disagree.
