Zambales

How dark the sky is at Zambales: Bortle Class 3, rural sky

The zenith sky here reads 21.87 magnitudes per square arcsecond. That is about 1.1 times the brightness of a pristine natural sky (22.0), the extra coming from artificial light scattered in the air.

Sky brightness and class come from the World Atlas of Artificial Night Sky Brightness (Falchi et al. 2016, CC BY-NC 4.0), with natural skyglow added. On the night, haze, smoke, humidity and the Moon set the real limit; see every Bortle Class 3 place.
