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

The radiance figure on file for Juneau is exactly 0.0, and a city of 31,572 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 "Juneau'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 Juneau

Wasilla, AK is about 571 miles from Juneau and has a trustworthy reading: suburban edge band. It's the closest usable stand-in until Juneau's own figure is corrected.

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

Juneau against the rest of the dataset
