Reddened Sunset Rainbow

Dramatic reddened sunset rainbow

The clouds broke just before sunset to give this dramatic reddened rainbow. The sun was only one degree above the horizon.


Composite of 6 images.

Bright rainbow at sunset

The falling rain was heavily reddened by the low sun so there is very little of the blue side of the bow. The bright region inside the primary contrasts well with Alexander's Dark Band, outside the secondary the sky is very slightly brighter too.


Right: Higher up the bow the blue end of the spectrum is a little more evident, but the bow is less intense.
