Rare Crepuscular Rays · **2 Likes**

A shot from yesterday from Barker Hill (SW of Western Australia), I had never seen anything like this before, the sun is going down BEHIND me in the west and this is looking east to the Porongurup Range. A knowledgeable friend just informed me this rare phenomena is called crepuscular rays.

Cool. Never heard of that phenomena. Right place and right time.

Interesting. Never heard of this either, but sure looks great!

As with the comments above, well captured.

Thanks people! Apparently caused when there is enough dust or particles in the sky to reflect the suns rays back causing the streaks.

That looks beautiful.

Nice shot! Rare? I've seen it here in Canberra quite a few times in the last five years.

Unfortunately I don't have any decent photos because it's the sort of thing that needs a really wide lens, and the widest I have is 16mm.
According to Wikipedia, they're anti-crepuscular rays, while the ones you see when the sunlight is shining from behind a cloud looking toward the sun - are crepuscular rays.

Cool shot. Never seen this phenomena.

Very impressive shot!

To be precise, these are anit-crepuscular rays, since the appear to originate from the anti-sun (the point opposite to the sun).
It is due to scattering (not reflection) by molecules rather than particles, by what is called Rayleigh scattering after Lord Rayleigh.

Learn something new every day! I see this often on the westward leg of my early morning commute, have wondered about it for years! Thanks for sharing, and teaching!

Lovely photo. Colors and composition highlight the effect.
