Weak Halo with Sundog

In addition to the weak 22 degree halo there is a sundog, well clear of the halo because of the sun altitude of 35 degrees. There also appears to be something in the upper tangent arc area.

The apparent brightening of the right side of the halo is actually a wisp of cirrus.

The wisp of cirrus has now moved toward the middle. The appearance of the upper tangent arc is largely unchanged, which confirms it is real.
