Hanford, CA: how dark is the sky here?

Hanford reads as urban on this dataset's scale. Sky glow overhead most nights. Typically only planets, the Moon, and a handful of the brightest stars are visible. That's brighter than 96.5% 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.

How far Hanford is from a meaningfully darker sky

The closest place in this dataset with a meaningfully darker sky is Lemoore, CA, roughly 8 miles away in a straight line, rated suburban edge. Road distance will be more.

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