How dark is the sky in Halland?

Sky darkness for 3 towns and parks in Halland, worked out from NASA satellite images of light at night (2025). None of them have skies of Bortle 4 or darker, where the Milky Way shows overhead. The darkest is Falkenberg (18.96, Bortle 6), the brightest Halmstad (18.30, Bortle 8).

Numbers like 21.95 or 16.97 are the brightness of the sky overhead on a clear, moonless night, in mag/arcsec². The scale runs backwards: a lower number means a brighter sky, from about 22 for a natural sky to about 17 in a city center.
