In Arabic there are many degrees of light when it comes to sunrise and sunset, more than in English or French.
Sunrise and Dawn has:
الدجى ، السحر,الصبح ,الفحر. الضهر
For sunset: الغرؤب الشفق ، الغسق
I find this brilliant because as a photographer there is indeed a difference between when the light comes or goes, the sun has is on the horizon or past it.
Here is an example of sunrise in Rabat earlier this year
Latitude 34
