Understanding Twilight & the Golden Hour
After the sun drops below the horizon, the sky does not turn dark all at once. Civil twilight is the brightest stage, when there is still enough natural light for most outdoor activities. Nautical twilight follows, when the sea horizon becomes hard to make out. Astronomical twilight is the darkest stage, after which the sky is fully dark and the faintest stars appear. The same three stages occur in reverse before sunrise, as dawn.
Great Falls sees its golden hour today around 06:14-07:15 and 19:38-20:38, framed by the blue hour at 06:01-06:14 and 20:38-20:51. As the sun's arc shifts with the seasons, these windows move with it.
