English: This photo of ice halos around the moon illustrates a number of relatively uncommon phenomena. First, the 22 degree halo itself (which is relatively common) as well as "parhelia" (moondogs) to the sides (the left one was hidden). A upper tangent arc appears tangent to and above the 22 degree halo, and finally a "parhelic circle" (although lunar, not solar) passes through the moondogs and the moon. Parhelia, upper tangent arcs, and parhelic circles are 73, 27, and 4 percent as common as 22 degree arcs, so this is a somewhat unusual event.
Even though this photograph was taken at nighttime, some color is visible in the arcs.
