Normal, IL: how dark is the sky here?

Normal's sky measures suburban here. Light dome dominates much of the sky. Only the brightest stars and planets stand out clearly. That's brighter than 69.6% 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.
