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.
Photographers in Río Cuarto get the golden hour at 06:19-07:07 in the morning and 18:58-19:46 in the evening today; the bluish blue hour falls near 06:09-06:19 and 19:46-19:56. Both windows move across the seasons.
