23 parhelia vs. tangent arcs


Here checking a faint solitary 23 parhelia stack against the 22° tangent arcs. For a moment it seemed that it was a poorly developed tangent arc and almost not worth the trouble to stack. Afterwards (something like half moth later) a quick comparison gives near 99.9% proof that we are dealing here with 23 parhelia and the case for tangent arcs is not valid.
