You have selected:
Optical Phenomena Volume III? Where are Volumes I and II? Ah…… they were disguised as Halos And Rainbows Volume I and II. Once Hygge made the remark that the former title did not cover all. He was right, so from now on I consider that issue to be solved.
Halos And Rainbows Volume II ended with the applicable title ‘At Loose Ends’ by Keelin. Very nice. Do I mistake or is that a part of the CZA with its bright and distinct colors you captured in ‘At Loose Ends’ Keelin? I love the play of light in these cirrus wisps.
So from now on besides halos and rainbows, also crepescular rays, iridescence, nacreous, noctilucent and whatever has to do with optics. And that makes me think of the incredible pictures of aurora borealis by Don. Optics for sure and enchanting even in black and white as Don proofed. I look forward to the pictures anyone likes to share in this topic.
To emphasize the meaning of he change of title: a start with ‘just’ some iridescence.
Not Able To Hide
A splendid solution and excellent introduction, Hans! And a lovely image to launch us all into this optic topic. So come out, come out, wherever you are, all wonders of light phenomena. No need to be camera shy.
Below, a moment that caught me by surprise as I was about to enter my local gym. A reflection in the tinted glass doorway stopped me in my tracks. Needless to say, exercise was postponed while I turned to capture the source of wonderland colors.
Reflection in tinted glass doorway
The real deal, but with contrast tweaked to tone down the sun’s blinding radiance.
PS: And yes, Hans, I think it may have been a part of CZA in ‘At Loose Ends’ (which also caused a delay that day in getting INTO the gym).
No better way then than to continue with these two pictures Keelin. It is really hard to be in time on whatever appointment being a cloudspotter. This iridescence needed full attention. I can find the reflection back in the real deal. Wonderful!
Through The Looking Glass
Oh so inviting, Hans! And wonderland beckons…With A Cheshire Smile
A very beautiful smile of a circumzenithal cat Keelin.
Some more iridescence….
Anti-crepuscular rays. Before I knew about there existence I captured this scenery in Italy (Gargano) at the end of the day in the spring of 2012. The sun was not that low already. I noticed the converging beams of light falling through the clouds. I never understood it until I got familiar with the optical phenomena a few years later and found the explanation on atoptics. Nevertheless most examples are captured at the moment of sunset in far less clouded skies so it still took some time to conclude these must be anti-crepuscular. It is my first and only example of this wonderful phenomenon.
Very interesting and beautiful picture, Hans. I have been looking out for this phenomenon. So far no luck.
There is another phenom that I notice, maybe related. The sky is red/pink on the opposite side of the sunset or sunrise. Not much at 90 degrees. When I search for anticrepuscular, I only get “anticrepuscular rays”. How about anticrepuscular light.
Here is one shot. Notice the very clear sky.
And while on this thread, a halo I captured on a hike last weekend. BTW, I finally caved in and subscribed to LightRoom. Wink-wink.
George I think I found the answer to your question about the pinks in the east: Anti-twilight arch or “Belt of Venus”.
Beautiful halo you captured! You wont regret subscribing to LR. I use it since this summer and I am really happy with the possibilities. You can improve the picture in a subtle way without doing violence to reality, but also manipulate it more vigorously and explore creativity.
Just quoting you with next sundog.
Thank you, Hans. And nice catch!
All beauties above, Hans and George! Especially love those iridescence images, Hans, with a hint of ocean in both of them. Mesmerizing!
And George, the branches of the tree add a joyful feeling to your halo image, as if it’s reaching up in celebration. Which is what I do when I see such wonders — even when it’s just on the tip of a passing cloud wing.
Ingenious Keelin. A great new category is born with the Wingtip Sundog. Love it!
Keelin, Hans, I like your sun dogs. Here is something from the sun, but not sure what. Maybe a UTA? This is about 10 minutes after sunset. The sun has set right below the color patch.
George, nice picture of a sunset. It is also my first thought that the color patch is a UTA. One can simulate the different appearances of the UTA with changing the height of the sun on atoptics (and also meteoros.de), but unfortunately the simulations don’t support a height below zero degrees, so I could not really verify the possibility. Still it is verifiable to see a UTA when the sun is at – or just under – the horizon. Very nice.
Keelin – The wing tip Sun Dog is Phenomenal!! Should be included in one of Gavin’s calendars, Cloud Of The Month, – – something.
Thank you, Hans, George, and Don for such kind comments. So fun to catch the dogs at play — especially when they’re shy. And George, what an amazing image that glowing smile is — kind of shy in its own way.
From the archives: a Moonhalo
Hans, the moon halo is very special.
Just took a look at the link Hans provided of the Rare Swedish Halos. If anyone has not done so, I highly recommend this. Makes me want to move to Sweden.
Thanks Hans !!
To continue on the sun dogs I posted on the new year’s day clouds thread, I was in the Yellowknife airport when I noticed it. I had a very poor viewing angle and I kept moving from window to window to get a better one. (The shot that I have posted I took from the tarmac as I was walking to board the plane. I only had a few seconds.) In the shots from inside, earlier, I notice something that is a bit of a puzzle for me. There is a sun and there is a bright spot below it (subsun?). And the sun dog is at the same level as the subsun. Also the parhelic circle is below the sun. I could not find anything like this on the atoptics site, maybe I did not search deep enough.
And further, this shot possibly captured a 44 degree parhelion, or at least a piece of the 46 degree halo. Look at the right side at the horizon level, about the same distance as from the sun to the sun dog. There is faint patch of color next to an object that raises above the tree line (perhaps the airport radar).
Great capture of the sundogs, George. A 44 degree parhelion is rare, so congrats. Unfortunately I don´t have an answer to your question about the height of the sundog that seems to be not at the same level as the sun itself. On the other hand I am sure you don´t see a subsun. A subsun must be just as far under the horizon as the sun is above. That is why you can only spot a subsun from a plane or from a mountain top. When the brighter spot on your picture is the sun, you might see a lower pillar beneath the sun (I think it is there), but that does not explain the extension to the left and right of the bright spot (like the parhelic) unless that spot is the sun. In that case the brighter spot above the sun is the puzzle.
I suppose you wanted to have more time to make pictures entering the plane. It is a lovely extra to your fantastic aurora experiences you already described elsewhere. I hope to see more of it!
George, your sundog and/or ? images above are truly stunning!
And Hans, your Moonhalo brings to mind lyrics of a lovely song by Greg Brown…
And there’s a ring around the moon; long, long time ’til day
Play me one more tune; please don’t go away
while fingers of the tree branch seems to hold the glow delicately in place.
Below, Mr. Crow stays for an encore by that other orb in the sky.
Beautiful! The crow is thinking, this halo needs a haircut.
This was also in YK, sun pillar and iridescence.
Like the crow I would also like an encore Keelin and George. Very niche hairy halo Keelin, and great sun pillar George! This makes me think that – when watching an optical phenomenon – I am always a bit disappointed when it vanishes and find myself afterwards trying to remember what it was like. But then there are still the pictures in the case the camera was at hand. The lyrics you quoted Keelin say it just as it is.
Thank you two. A lovely composition in your capture of iridescence and sun pillar, George. And a playful feeling is evident in your Scattered Sundog, Hans. You know how those puppies like to dash about!
Two very nice discrete dogs, Hans and Keelin.
George – (sundog? photo) : don’t know; don’t care. This photo just speaks to me. I would be proud to hang a 10×20 in my home.
Stay, Stay! But unfortunately they don´t Keelin. very nice composition with this tailed doggy in the starring role.
For something else I would shout: Come! It is the season that nacreous clouds can be observed over here although it is a very rare phenomenon because it is more often seen in more northern regions. I spotted nacreous in february 2016 for the first and last time. There was first a colorful appearance which I mistook for iridescence at that time but I also spotted one formation a bit later the same day and it does not look like the nacreous with all the colors. What struck me is the resemblance to a picture someone took a bit more south and got published on atoptics. Look for the seventh picture (taken above Delft, Netherlands) on the link: Two types PSC explained
On this link the difference between the two types of PSC´s are explained and their relationship with the ozone in the atmosphere. The seventh picture shows PSC type I (being just red). My picture above Haarlem shows the same formation (I think).
How wildly lucky, Hans, to have had a sighting of nacreous clouds! I do not believe it will be your last. And thank you for the link to atopics explanation of these fabulous formations. Indeed, your lovely image above seems to match the description of type 1 PSC. Did that make your toes wiggle?
I do wish I could see further north to catch sight of nacreous, but for now, a little webworker has me stuck in place.
Ah. the toe-wiggling was somewhat postponed but nevertheless took place when I was sure afterwards what I saw.
Be careful Keelin not to get stuck like the halo did in this fine web!
No nacreous now but the familiar iridescence while waiting for a new opportunity.
What a delicious shot, Hans! A feast for the senses.
Another One On The Wing
For too long no feedback on this one Keelin. It is a true beauty on the wing!
