Details:
in the afternoon of September 29th in Curitiba, southern Brazil, I saw some atmospheric phenomena in the sky. They were ice halos. This photo shows two halos, called circular halo and circunscribed halo. They develop around the sun, and the circunscribed runs out of the circular. But they are coincident in the upper and lower points, thus brightening the halos in those regions. The lower brightening point can be seen just above the trees, between two pillars.
A careful analysis may show two extra halos, very faint. They are the infralateral arc (near the left border) and parhelic circle (extending from the sun to the upper left corner).
