Il existe des contrails & des chemtrails. C’est vrai. Il existe des tests de charge sur les avions. C’est vrai. Mais, qui dit qu’ils pulvérisent de l’eau ou du jus d’orange ? Qui ? Qui vérifie ?
Les avions atterrissent quelque part, où ? Où sont les photographies des avions ? Avions anonymes croisés sur le tarmac ?
Un avion n’est pas un hélicoptère. Il ne se pose pas à la verticale. Pour atterrir il descend. Photo ?
Combien de vols quotidiens entre LA et Denver ? Combien font des chemtrails ?

the probability suggests it is unlikely at that time of year…but not impossible. Unless the sun cannot reach 58 degrees in the sky- Can it in MI in Dec (i don’t know)? If not then it is Not a CHA.

So, you have move from probability to empirical data. The empirical data suggests that is an Arc. It is identical to an Arcs description- this description – to me- depicts exactly what you filmed:

” Look for the brightly coloured circumhorizon arc…when the sun is very high in the sky….Often only fragments are visible where there happen to be cirrus clouds – the individual patches of cirrus are then lit with colour that can be mistaken for iridescence.”

the event was at noon when the sun was highest , the splotch of iridescence was lit on a patch of thicker cirrus clouds. The arc IS a halo. If you look closely- you can almost see a curve to the splotch- could just be me. You said there was “NO SUN around the arc AT ALL”- This fits the description which says a CHA is twice as far from the sun as 22 degree halo; “about 2 hand spans”

The film you took looks identical to pictures of CHA’s-

You said you saw others throughout the year…when the probability only increases the likelihood of occurring as they are “common in the USA”…

Perhaps it was only iridescence.

Be that as it may- they sky you filmed was filled with ice clouds and thus the possibility of some atmospheric optical event involving the refraction of light with prismatic effect is to be expected. Can you elaborate as to why you find this alarming?

Can you think of anything other than ice or water that would refract light with such effect?

Well, perhaps the term ‘chembow’ is a misnomer, because it’s more like an iridescent splotch. There is no ‘bow’ about it at all.

Nor are there chemicals.

Although technically water is a chemical, so you call could a rainbow a chembow if you really wanted to.

And though you may not be able to tell from the video, it was not that high up. In fact it seemed damn near overhead at the time

Priceless.

What’s overhead got to do with it? Pretty sure the sun can pass overhead but it’s still a very long way away.

Your video, to me, shows cirrus clouds. That makes them high up. Can you explain how you determined how high they were?

Again, this was not the only one, but the only one I was able to capture on video. Many of the others were larger, and splotchier.

There was NO SUN around the arc AT ALL! There were NO HALOS.

And it was not a part of some larger cirrus cloud that appeared iridescent, but the whole thing. And though you may not be able to tell from the video, it was not that high up. In fact it seemed damn near overhead at the time, and the people around me that I was pointing it out to were just as surprised as I was because nobody could remember every seeing anything like it.

I’ve lived in MI now for 9 years, and I have yet to see repeated the string of these sightings like there was that December. Believe me, I was keen to observe them this year, didn’t see a one.

So, if you can be so confident, that’s good for you. I have been up and down the ‘atmospheric optics’ site and I still don’t concur that it’s CHA or CZA, based on location, conditions, and personal observation.

Stay Sovereign!

It does, however, look almost identical to the pictures of the CHA and the fact that the time of day and that it is a “splotch” is consistent with the description:

” Look for the brightly coloured circumhorizon arc…when the sun is very high in the sky….Often only fragments are visible where there happen to be cirrus clouds – the individual patches of cirrus are then lit with colour that can be mistaken for iridescence.”

…and beauty is in the eye of the beholder- I thought it was pretty cool looking.

I am confident it was a CHA.

You often only get part of an arc, which can look like a “splotch”
