At the End of the Rainbow

Who'd have thought that Budgen's was at the end of the rainbow!!!

We've had lots of rain and several thunderstorms this afternoon. After the last one I quickly popped out to post a birthday card at Budgen's and saw this wonderful double rainbow. I cleaned the rain gauge in my garden a couple of weeks ago and it shows we've had 2 inches of rain in that time. 

'Double rainbows occur when light bounces inside the water droplet more than once before escaping, the spectrum of the second arch will be reversed. Between a rainbow and its double the sky is darker because light reflected in raindrops in this part does not reach the observer. This area is called an Alexander's band, named after Alexander of Aphrodisias who first described it in 200 AD.'
