Ripon, CA: how dark is the sky here?
Satellite radiance puts Ripon in the suburban band. Light dome dominates much of the sky. Only the brightest stars and planets stand out clearly. Only 75.2% of the 3,206 cities measured here read darker than Ripon.
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.
How far Ripon is from a meaningfully darker sky

Riverbank, CA is itself still a measured city, not a designated dark-sky park, this only compares against the 3,206 places this dataset covers.
