Upper tangent arc, 22 degree halo, sundog.
Upper tangent arc, 22 degree halo, sundog.
2003/9/6 16:36 EDT. A flat upper tangent arc above the 22 degree halo, and a sundog at left. Also there is a rare Parry arc above the upper tangent arc. In addition, there seems to be a straight line from the sundog to the top of the 22 halo. Could the straight line be an upper Lowitz arc? Nikon coolpix 995 snapshot. Pittsburgh, PA.
