Strange phenomenon Photo

Photographer’s Note

This picture has been taken yesterday at 7 o'clock PM. I have never seen the arc like this.
The picture is in the good way (not rotated) Another one has been posted in W/S.
Note: The circumzenital arc is the most beautiful of all the halos. The first sighing is always a surprise, an ethereal rainbow fled from its watery origins and wrapped improbably about the zenith. It is often described as an "upside down rainbow" by first timers. Someone also charmngly likened it to "a grin in the sky".
Look straight up near the zenith when the sun is fairly low and especially if sundogs are visible. The center of the bow always sinwards and red is on the outside. It is never a complete circle around the zenith, that is the extremely rare and never photographed "ken arc".
(These informations have been given by a friend who is "Meteo")
For this photo, the estimated angle is 70°.

Interesting photo, looks like that you are in space and looking down on the world.

c'est étrange !
je n'avais moi non plus jamais vu d'arc en ciel dans ce sens là !

très original.

et intriguant !

j'ai du coup fait quelques recherches, il semblerait que les arcs-en-ciel forment un cercle, donc on ne voit la partie la plus autre parce que l'autre morceau est situé "sous l'horizon", et donc observable que depuis des hautes montagnes et en avion...

Really strange photo. I would like to know if you used a polarizer (the upper dark part of the picture otherwise is really strange) and the aiming of the camera: Was the sun behind or in front of you? What was the elevation angle? And the effective focal lenght?

Strange, but to be honest, I prefer the whole view in order to see its ends.

Cet arc est provoqué par des cristaux de glace en haute altitude où il fait -40°.
D'habitude c'est plus petit, celui là est phénoménal.
Intéressante composition naturelle.

Très très bonne photo d'un arc circumzenital. Bravo!
En effet je regarde toujours le ciel: de jour comme de nuit
(une habitude d'enfance). J'ai une photo d'arc ave 2 sundogs
et un halo a 22/o (une rareté). Une photo comme la tienne pourrait intérésser EPOD (Earth science picture of the day)
a http://epod.usra.edu/. Ils publieront peut-être mon nuage (une autre photo) début novembre.
Bien à toi!
Mauro
