Geograph - photograph every grid square

A little earlier there had been thunder and lightning with squally rain. As the storm passed and the evening sun dropped below the cloud layer, an increasingly vivid double* rainbow appeared over the bay.

*possibly triple? Look closely at the brighter, left-hand bow and there appears to be a third, vertical 'bow' rising from the same point. Wikipedia suggests that these 'reflection rainbows':
'may be produced where sunlight reflects off a body of water before reaching the raindrops, if the water body is large, quiet over its entire surface, and close to the rain curtain. The reflection rainbow appears above the horizon. It intersects the normal rainbow at the horizon, and its arc reaches higher in the sky, with its centre as high above the horizon as the normal rainbow's centre is below it. Due to the combination of requirements, a reflection rainbow is rarely visible'. So, it would appear I was lucky to see this.
