The person making the observation definitely stated the bow was behind
him. I
don't recall him indicating there was a body of water nearby. The most
important part I gleaned was the prescence of smoke near the Sun-I guessed
that
that scattering effects on the sunlight by the smoke may have had an
effect, but
I am not sure. Thanks.
