What the night sky looks like over Longview, WA
Longview reads as suburban edge on this dataset's scale. A noticeable glow near the horizon. Brighter stars and constellations are easy to pick out; the Milky Way is washed out. That's brighter than 38.6% of the 3,206 US cities in this dataset.
The number comes from orbit, not a stargazer's logbook, so treat it as an estimate of sky glow rather than a certified Bortle class.
