Tangent Arc?

I got to thinking after taking another looking at my arc photos, that this shot may show a weak tangent arc above the also weak 22 degree halo around the sun.

Possible tangent arc with circumzenithal arc above, also showing left sundog and weak 22 degree halo.
Photos were enhanced as described in my circumzenithal arc post; lower photo is two photos stitched together. Better sundogs and halo can be seen in the circumzenithal post.
