Anticrepuscular Rays

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. IMG_2751sq 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.” IMG_2753sq 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.

Still waiting for Hurricane Isaac

In the week+ since we were warned that a tropical storm was brewing down south and looked to be heading towards Pensacola, we’re still waiting for the effects. Heck, we’re still waiting for just about¬†anything¬†from this system that doesn’t look like any other day on the Gulf Coast / Florida Panhandle.

On Sunday night our school district cancelled classes for Monday and Tuesday. I hopped on the bike that night and went around taking pictures of the clear skies and beautiful sunset down by the water.

Monday night, Lise and I went out and took more pictures – what a contrast! The clouds and strong winds are about the only thing that tell you that there’s a hurricane out there, but the difference between the top and bottom picture, taken almost exactly 24 hours apart, is striking!

Still waiting, Hurricane Isaac!
