I know this is a terrible picture of a rainbow, but I've never seen one of these before [by which I mean morning rainbow, thanks to Amy for pointing out the ambiguity] and always wondered if they existed. I assumed they did, that they'd have to.
This was taken less than an hour ago, at 7:47 AM EST. This is a morning rainbow.
I took two photos. As lousy as that one is, it's the better of the two.
See for yourself:
On second thought, maybe it's not worse, the non-zoomed version. It's sort of more graphically incongruous in the second one. Obviously it's not a composed shot, it's a roll down my window at a stoplight and snap this in a hurry shot.
