This subdued sunset brought to you by the soot in the air contributed by hundreds of western wildfires. Hopefully you’ve been off grid and out of the way of these plumes. Such a Pall changes not only the air quality but the amount of solar radiation that makes it to the surface.
This image is my best try to get the scene exactly as I remembered it. The wedge of smoke from various Montana fires were moving this way. The cloud front was forming in advance of the smoke pall with the smoke moving with the front. I have seen this develop before and got the heck up the hill well over an hour before sunset. I figures that as the sun dove behind that jagged bottomed cloud, that shadow would get projected in the smoke below. The result is a fan of crepuscular rays radiating outward away from the sun well above the cloud deck. This is a fairly expansive display. Taken through a very wide lens at 24mm .
This is the second nice crepuscular display I have seen from this years smoke/brown season. They are somewhat predicatable to me but to get the ducks to actually line up is an entirely different matter lol. This would be a nice candidate for a mirror/mirror ART treatment I’m thinking… I’ll have to make a note to reflect this back on itself. I bet a nice face will appear magically.
I call this kind of sunset with divergent crepuscular rays a “Crown Sky”. The rays reminding me of a royal crown but it is also suggestive of a massive cathedral with a starburst at the focal point. I really don’t see too many of these. Considering the nature the particular environmental conditions necessary to create this.
OK here’s how it work. The light from the sun is passing under the lowest cloud bank just on top of the white disk. That light is stopped by the shape of the puffy bottom of the cloud surface. This creates shadows on the clouds/ice toward the camera. The “Rays’ you are seeing are the opposite of the shadow lineson the foreground of the effect. The lit up parts of the rays are illuminated by the light passing under that lower cloud bank. So that clouds bumpy surface profile is reflecting off the cloud deck. As a final “nice tough” here of course also has to be some falling ice crystals (hexagonal plates falling oriented like parachutes) to light up to really make it pop like this. So several things have to be happening at just the right time for this phenomena to occur.
I’ve seen these rays pointing upward like this capture as well as in a down facing divergent crown. I watch a lot of sunset/sunrises and I’d say these occur at a 1 in 500 rate or so. I have a handful of Crown Sky Captures over my travels.
This inverted Crown Sky is one of the more rare skies I occasionally get the privilege of photographicing.
All The Crepuscular rays are diverging away from the position in the sky the sun is in. The Monster face was obvious and natural. I did nothing to the form of this image.
I’m typing this on Wednesday night. It will post on most social media and several FB forums automatically on Friday morning :).
This inverted Crown Sky (crepuscular rays) pointing downward and outward. The perspective of a shot like this is hard to understand unless you know that this is also a VERY wide shot over 120 degrees across.

It was Windy so the Reflections of this Starburst Sunset (A double crown sky) were ripply. A Starburst is one of the rarest crepuscular phenomena. This was two nights ago out on state land….. Nice little lake down there…
