Antioch, CA: how dark is the sky here?

Antioch's sky measures suburban edge here. 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 32.9% of the 3,206 US 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.
