BD … Bürgerliche Dämmerung – Lesen im Freien möglichen (Tiefenwinkel bis 6 Grad)
ND … Nautische Dämmerung – Horizont und einige Sterne sichtbar (Tiefenwinkel bis 12 Grad)
AD … Astronomische Dämmerung – bis zur maximalen Dunkelheit tiefer Nacht (Tiefenwinkel bis 18 Grad) *
* Infolge zahlreicher irdischer Beleuchtungsquellen ist vielerorts nach dem astronomischen Dämmerungsende kein völlig schwarzer Nachthimmel zu erleben; diese Aufhellung wird auch als Lichtverschmutzung bezeichnet.
