adding some seahorses and sherbet to this techni-colorful collection!August 13, 2022 at 11:12 pm in reply to: Kelvin Helmholtz Instability or fun “wave-on-wave” clouds? #543913
is it OK to jump on Ramona’s thread instead of starting a new one? let me know if not, and I’ll start a new thread.
Anyway, same question different clouds. i’ve always wanted to see fluctus but I didn’t think it would look like this… Am I seeing KH here?
a giant poodle for you wonderful people. so many good animals (and then some) here!
thank you so much, Hans!
Yes, bit by bit will be the way… and I’ve spotted another parhelic circle w circumscribed halo combo since this thread :)
keelin, that is one garnish I could go for! And Hans, another dog, perfect. They have been cropping up all over
keelin, that dog is clearly having the time of its life! It really is evocative, I can almost feel dog drool coming in through the back window of the car :)
and hans, i hope you and your friend were able to stay as cool as possible. It really is, as Duncan has said, most uncomfortable.. If only we could be like that bird on a wire, and just take flight in the cool breeze
speaking of dogs, just this morning I spotted a passing dachshund straining on its leash

wow. this is like going back to school. i love learning. And I don’t get to do it much these days. So I am very grateful for this thread.
It is very exciting about the potential 23 plate arc. I’m so glad you were able to get in touch with him. how satisfying to spot something like that. And that I have these amazing phenomena available to me just outside the door, that’s priceless, and makes me all the more curious. Thank you for spotting it! I’d never even heard of it before. You’ve contributed to my learning experience.
I looked into an app to shoot RAW, but i’ll have to wait until I can afford it. I definitely want to try it.
Fiddling with the last photo I added above, I suspect there’s a parhelic circle there, do you see it? here it is with some screenshots from a quick google search. I included those because of the angle. The arms of the circle are raised, so i was suspicious it was a curving contrail. But I guess it depends on the angle of the sun?
so much to delve into here.. i’d also like to upload what I think is a 9° halo with an interesting addition, but let me just quickly answer your two questions:
that’s exactly how I did it, through the ‘submit an observation form’… but I don’t remember if the form gave me tech issues or not.
images 1 & 2 and images 3 & 4 are two different days, and image 5 is another different day. so three different halos, three different days. does that make sense?
ps, edited to add two more halos of interest:
am i correct in thinking the both different halos here include a 9°, and the second includes a circumscribed halo? and… is that a very sneaky cloud? or is it the PC?
yes, I was wondering about the colorlessness! I thought a fog bow was the only phenomenon that would appear as a colorless arc.
also, I should apologize, I sent him a total of 11 images, one of which contained a sun dog (and the partial parhelic circle) as it related to the first halo above. The others pertained to the item with an appearance of a 9° halo which keeps looking hexagonal to me! and i shall remain stubborn about that, even if it is indeed one of life’s great illusions… :)
As you can tell, I’m new to this, but was also surprised when he said UTA. He sent me this fantastic tool: https://atoptics.co.uk/halo/colsolat.htm to show the different angles of arc. But even with this tool I don’t see it draping over in a concave way as it does in the photo. Of course I have never heard of a 23 plate parhelion, but now I have, and am very intrigued.
If it helps, halos 3, 4, and 5 above were all in may and june of this year, all between 4-6pm in easthampton, mass. pix 1 & 2 are june, same location, but around 9am
“The only possible thing left to do is to send my answers to Alec” i’m not sure if you’re asking me to, but if so, of course!
well, i’ve heard back from alec, thank you, for that recommendation!
here’s what he said
“With regard to your question about hexagonal looking halo, by and large this is either a digital artefact or lens aperture effect and not a real halo. This kind of effect appears very frequently; after a while you just learn to ignore it.
With regard to the halos you have captured, there is nothing really unusual and most of them are very common. From what I can see you have photographed 9, 18 and 22 degree halos, an upper tangent arc, a sundog (singular parhelion plural parhelia), and part of the parhelic circle.”
Part of the parhelic circle! I didn’t know that was available to me in western Massachusetts and i’m utterly delighted that that’s the case.
hans, I’m curious if that is what you had picked up on?
oh, I definitely want to share it here :)
The 9° halo looks hexagonal to me. And I figure it’s just a magic mistake. I mean, that’s not possible is it? that’s not possible. It’s got to be magic… ?
(when I say magic I just mean clouds playing lovely tricks)

just wanted to say wowie zowie, miriam, that is one compelling cloud scenario!
what a comfortable dog bed, ruth! and thank you for your welcome. here’s another heart, one can never have enough
hello hans, and thank you for these links. it’s very exciting, thinking about these phenomena, isn’t it! i will submit my photos to the Halo Vault, along with these… does anyone see anything strange here? i imagine it’s just cloud playing tricks…
oh! there are circumscribed halos here… I keep forgetting what they’re called and they’re relatively new to me.
But am I correct? And is there other stuff going on here? Is that smaller circle of 9° halo or a corona?
and is there other stuff going on here? Is that smaller circle a 9° halo or a corona?
Thanks so much.
