Be sure to read the explanation; who'd have thunk it? In all my years I have never seen this phenomenon.

I myself have also never seen this phenomenon before myself, but have read about it before on. Another good example. I will have to keep my eyes open the next time I see crepuscular rays.

Cool, from the same site even! You'd think, with allt he years I've spent on the water, I'd have seen this once or twice, eh?

It's a matter of knowing that it pays to look. Whenever you see a nice display of crepuscular rays, always look at the opposite horizon and check. Saw this one in New Mexico a few years back:

I suppose if there are nice rays in front of you, you look to the front and not behind you...

Wikipedia also has a short article along with a panoramic photo. 180 degree fish-eye view of anti-crepuscular rays.

Robert, also note in your OP that the link is only for the current day APOD. Here is the perma link to the image you referenced.

Nice example. I will most certainly look behind me the next time I see crepuscular rays.

Thanx, I changed the link to the permanent one.

Well, that's the thing of it; I have always been in the habit of shooting AWAY from sunsets, I love the light like that. I mean, I'm sure I've missed some, but still....

Great shot btw.

Like many sky phenomena, they're often subtle. So again, if you're not looking for them, they're very easy to miss. My shot was contrast enhanced and I'd be very shocked if the APOD one wasn't also. That day at Taos, several people noticed me shooting away from the sunset and asked what I was shooting. When I pointed it out to them, everyone saw it and suddenly there were a half-dozen of us looking and shooting the other way, oohing and aahing the whole while. But before that, nobody noticed.

round here (Colorado), I seem to see them all the time. I kind of like to shoot weather, etc. so I look for that stuff. Wonder if the mountains funneling light up and then through the clouds has a little to do with it? Even though I see it a lot at dawn going towards the mountains too.
was in thick traffic on the way to work one day last month and there were some awesome ones...couldn't get out of traffic to get a shot though....darnit.

I think the light has to be broken by holes in the clouds or irregularities in the Earth's surface (typically trees or mountain/ridges) at the horizon point masking the light source in order to form the rays, or more accurately the shadows which distinguish the rays from just an even sheen of sunlight.

Wow - thanks for sharing the link! Weather phenomena amaze me and I've shot lots of crepuscular rays for stock photography - now I'll always know to turn and look in the other direction, too. :)

Hi everyone. I am new here and I wanted to comment on anti-crepuscular rays. I took some pics recently when I was up in the Klamath Basin in Northern California. I saw this dark starburst in the sky, opposite the sun. It was about a couple hours before sunset and it was above the horizon a little ways with central point...not shooting up from the horizon but more like a starburst hovering above the horizon. Also, there was not a cloud in the sky East, West, North or South.

Here is a wide shot showing the horizon. It was almost imperceptable...but I just noticed something was there...

Aye Matey, but have ya ever seen the green flash? It's a sign that a trapped spirit has escaped from Davy Jones' Locker.
