Avondale's reading looks wrong, and this site says so rather than hide it

Avondale's satellite reading came back at exactly zero, which is not a real measurement for a city of 96,609 people, it means the sample point most likely missed the lit part of town, landing on open water, a shadowed hillside, or just a bad coordinate. Real cities this size do not read true zero.

This is flagged instead of shown as a normal result because reporting it as "Avondale's dark sky" would be reporting a data error as a fact, see the data quality guide for how this gets checked.

Because Avondale's own coordinate is what produced the bad reading, that distance figure is itself approximate, not a confirmed measurement.
