The orange coloration happens at dusk and dawn, just as we see the sun or sky at that time. When it is born or set, the sun is so close to the horizon that the light reflected and spread by a thick layer of the atmosphere. This atmospheric barrier imposed by the pollution of the brazilian dry winter is an opportunity to photograph the sunset, but it's a dilemma faced in a country that is the champion in carbon release by forest burning.
