I need to calculate sunset, evening twilight, morning twilight and sunrise. Libnova has methods to calculate sunrise, transit and sunset, but I can't find methods for calculating twilight. Can anyone help point me in the right direction for how to use libnova to calculate this?

Kind regards,

Lasse

Sorry, I figured it out. The solution is to use ln_get_solar_rst_horizon with a horizon of -6.0 degress for civil twilight
