The above photo shows a halo phenomenon known as the upper tangent arc. When cirrus clouds contain columnar ice crystals aligned so that their axes are all in a horizontal direction, this type of arc may be produced. A characteristic of this arc-shaped patch of light is that it's directly above the Sun(it bends upward away from the Sun), and it's approximately 22 degrees away from the Sun itself-about 2 fists held at arms length.  1, fiche 2, Anglais, - upper%20tangent%20arc

The 22° halo is most common, but other halo forms are sometimes seen. The tangent arcs to the 22° halo can appear if the sun’s declination is less than 32°. One is called the lower tangent arc to the 22° halo, and the other is the upper tangent arc to the 22° halo. The shape of these tangent haloes depends upon the sun’s declination. If the sun is close to the horizon, the two upper arcs angle sharply away from the 22° halo. As the sun rises higher in the sky, the tangent arcs move toward the 22° halo. When the sun’s declination reaches 32°above the horizon, the lower and upper tangent arcs make contact, and the resulting ring is called the circumscribed halo. It touches the 22° halo above and beneath the sun. When the sun is just above 32°the circumscribed halo resembles a double oval. As the sun rises higher it becomes increasingly circular and draws nearer to the 22° halo. When the sun’s declination exceeds 70°, the circumscribed arc nearly coincides with the 22° halo.  2, fiche 2, Anglais, - upper%20tangent%20arc

Un peu au-dessus ou au-dessous de l'astre lumineux [soleil], à la distance de 22 degrés, on peut fréquemment voir des arcs supérieurs et inférieurs tangents au petit anneau. En fait, on observe plus souvent les arcs supérieurs; ils ont souvent de belles couleurs. [...] Sur l'image suivante, on voit un arc tangent supérieur.  2, fiche 2, Français, - arc%20tangent%20sup%C3%A9rieur

A tangent arc is a patch of bright light that is occasionally observed along a halo. This occurs when sunlight is refracted by falling hexagonal "pencil-shaped" ice crystals whose long axes are oriented horizontally.  3, fiche 3, Anglais, - tangent%20arc

tangent arcs. ... The most common of these are the upper and lower tangent arcs to the halo of 22°. They form separate arcs when the sun is low, but as the sun climbs they join to produce the circumscribed halo. These arcs are explained by refraction through the 60° prism sides of columnar crystals oriented with their long axes horizontal.  4, fiche 3, Anglais, - tangent%20arc
