    Spectacular Rainbow

    This was a perfect setup for a double rainbow, with light rain still falling but the setting Sun shining unobstructed through perfectly clear air.

    Nice!
    The greatest journey of all time, for all to see
    Every mission makes our dreams reality
    And our destiny begins with you and me
    Through all space and time, the achievement of mankind
    As we sail the sea of discovery, on heroes’ wings we fly!

    Yeah, but it's not "Double Rainbow Guy" spectacular...

    There's a name for why the area between the bows appears darker. I'll have to look it up.

    Meanwhile, may I add one? Not so bright or double, but a very complete arc!

    The primary rainbow is a caustic at the edge of a wide patch of reflected light within its arc. The secondary rainbow is an inside-out version of the primary, so it's a caustic at the edge of a ring of reflected light outside its arc. Therefore, the area of sky between the two rainbows is darker, because it lacks the reflected light associated with either the primary or the secondary.

    Incomplete and only faintly doubled but if you listen closely, you can almost hear it sizzle as the end touches the water.

    Here's a faint, but potentially puzzling, pair of rainbows for you. i ran for half a mile to reach my camera and a useful vantage point before "God's V-sign to the world" faded away:

    At first I thought "Wow that's crazy." - and then I remembered where I've seen this before.

    One is due to reflected sunlight off the water.

    Yeah, they really took off after they ditched their original name, Alexander and the Peripatetic Aphrodisiasts. It never fitted on the singles sleeves.

    My favourite rainbow phenomenon is the band of supernumary rainbows you sometimes get inside the main bow. You can't always see them.

    Thanks for that colorful run! Remarkable catch! My first thought for the "V" would be to consider water reflections, but perhaps some bright storm cloud top near the Sun and closer to the horizon for creating the effect. My last shot is the illumination from the bridge gate rooms. [I was hoping others would ask you to be more allusive so I could reach something more conclusive.]

    I suspect name copyright entanglement with some heirs of Aristotle.
