I am a lifelong fan of beautiful meteorological phenomena, including being a fully paid up member of the Cloud Appreciation Society. So imagine my joy when, as I trudged home following yet another interminable day of thesising, the sun emerged in the midst of a rain storm. I glanced skywards, knowing conditions were perfect. And I wasn’t disappointed, before long I spotted a lovely rainbow. And THEN, joy of joys, I saw that there was a glimmer of colour outside the rainbow. Could I be about to see the mythical Double Bow? As I rounded a corner, the original rainbow increased in intensity. And, for just a few seconds, a faint second rainbow was visible. I just about managed to capture it with my phone.
