Details:
Altough difficult to see visually due to the sky brightness, this photo shows some halos caused by ice crystals. Present here are the 9-degree halo, 18-degree halo, 22 degree halo and circunscribed halo. The first two halos are caused by pyramidal ice crystals. I was quite surprised when I saw all those halos. Viewing them through the viewfinder of the camera was easier, because looking directly at the sky did not reveal the halos very well.

Actually, the 18 degrees halo in the image is not the 18 degrees ring itself, but its so-called column arcs, left and right of the sun. Somewhat like the common parhelia. Indeed a faint common 22 degrees parhelion is present too. The bright arc in the top can be determined as the 23 degrees column arc. The 23 degrees ring itself is present too, and is likely the halo which was assumed to be the circumscribed halo. A valuable picture of an amazing display. Good work!

- error - not the COLUMN arcs of 18 and 23 degrees, but the PLATE arcs! caused by oriented plate-shaped pyramidal crystals.
