One thing about Pensacola sunsets that has blown my mind since we moved here is this optical illusion known as anticrepuscular rays. It’s not an everyday thing, but it’s frequent enough that I’m not surprised when I see it. This shot is from Christmas Eve just as the sun is setting. Because of how those rays appear, one might think that this is looking due West, after the sun has actually set. This is not the case, however! This view is to the East, and the point where the rays converge is the exact opposite of where the sun is setting in the West.
Quoting the website “Atmospheric Optics” (atoptics.co.uk): “They appear to converge towards the antisolar point, the point on the sky sphere directly opposite the sun. Like crepuscular rays they are parallel shafts of sunlight from holes in the clouds and their apparently odd directions are a perspective effect. Think of a long straight road, it converges towards the horizon but turn around and it also converges to the opposite horizon.” Sometimes I get so focused on the sunset itself that I forget to turn around and see if this effect is in play on that night. Thankfully I did, as this is one of the most amazing displays of anticrepuscular rays I’ve seen yet.
