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

The radiance figure on file for Blythe is exactly 0.0, and a city of 17,320 people does not genuinely read zero light from orbit. That points to a sampling miss, the wrong coordinate, water, or unlit terrain right where the sample point landed, rather than an actual dark sky.

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

The nearest reliable reading to Blythe

Lake Havasu City, AZ is about 61 miles from Blythe and has a trustworthy reading: suburban edge band. It's the closest usable stand-in until Blythe's own figure is corrected.

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