A beautiful image showing ice halos as we more often see them.    The familiar 22° radius halo circles the sun showing that tumbling cluster crystals were in the air.   At its top is a hint of an upper tangent arc formed by hexagonal column crystals drifting with their long axes more or less horizontal.   A UTA is very often evident as a brightening at the 22° halo's top.  The picture is completed by a sundog or parhelion to the sun's left and right.
