I agree totally with Les. These twinned bow things seem something
completely different than ordinary supernumerary´s (and
talking about the internet pictures mentioned by Les above). The way they
branch seperately and the way they look on behalf of colors (same clear
area of red etc in both bows, similar color pattern) discern them by far
from supernumeraries.
Funny thing, we don´t have this twinned bow phenomenon as its own
case in the new literature in atmospheric optics. And in the old stuff
mainly Minnaert presents a not-sorted-out, chaotic drawing collection
of all kinds of rainbow "anomalies", just like later Corliss. Both
probably have a large proportion of poor-level observations, especially
Corliss who took uncritically almost everything "anomalous" in.
But this photographed stuff is real and its exciting stuff, particularly
since its so similar (=a class of its own).
