IMHO, rainbows are indeed the most beautiful thing in the world. Make your own with a spraying hosepipe on a sunny day and smile.

I wonder if it's possible to view a rainbow and a sunrise/sunset at the same time  ...

hmmm. Good question, if it were possible that would be very beautiful!
 Now then,
You see a rainbow when the sunglight hits the wet air and refracts within each water droplet. This process splits the light out by wavelength into the colours of the visible spectrum. This light bounces back from the raindrops into your eye.
For this bouncing to work for you, I think that the sun always has to be behind you. I've looked at lots of rainbows and I'm *sure* the sun was always on my back. So, afternoon rainbows are to the east, and morning rainbows to the west, and you can't look at the sun and at a rainbow at the same time, since the rainbow is a kind of reflection of the sunlight.
I don't think that you could see a rainbow at dawn or dusk, because the sun, the water droplets and you are at the wrong angle for it to work. Also I don't suppose the sun would be bright enough to refract strongly...
Well, obviously you cant see rainbows in the dark ~ only moonbows then... but 'dawn' and 'dusk' are fairly loosely defined terms. You might be lucky enough to see a tinted sky at dusk with the sun low but still bright and a rainbow to the east. if so, that would probably be the most beautiful thing in the world.

Of course, one reason against being able to see a rainbow and a sunrise/set at the same time  --the light's already *been* refracted.

ooh! Thread awake!
I saw a setting sun make a rainbow at the weekend. I was with some pals driving over the Yorkshire Dales. It had been perfect rainbow weather, and we had seen about 8 rainbows that weekend. Late in the day, at 5ish, with the sun very close to the western horizon there was a part rainbow in a low thick cloud to the east.
Stunning.

It was very close to the military base at Fylingdales, and I was sort of wondering if they were looking...

I DONT KNOW WHETHER IT IS THE MOST BEAUTIFUL THING IN THE WORLD AS I HAVE NOT SEEN ALL OF THE WORLD. BUT I DO KNOW HOW TO REMEMBER THE COLOURS. ROY G BIV (YEARS OF PHYSICS)
