No, I hadn't been drinking, and my wife and mother both were also
witnesses. I am ever so sorry that I had no camera.

Subject: Re: [METEOPTIC] double rainbow?
hi, James
About your double rainbow, I dont want to suspect that you were drunk...
But I think that a reflection upon water could not produce your "golden
arches". A horizontal displacement can only be created by a reflection
on a
vertical surface. This way the two sources of light (procucing the two
centers
for the two different bows) are also horizontal.
But how could you get a vertical surface big enough to lighten a whole
rainshower? Strange indeed.
I seem to remember a drawing - could be in Greenler's wonderfull book,
if not,
it could be in any of the numerous websites I have visited about
atmospheric
optics - from an ancient (one century or more?) observation of such
double
rainbows. No explanation was proposed...
Well... Waiting for other reactions...
Regards,
Pascal
