There's no need to guess where the pot of gold is in this shot of a rainbow caused by the midnight sun. The photo was taken by Mika-Pekka Markkanen in northern Finland as the light was still strong enough to form a rainbow in Kuusamo, just 37 miles south of the Arctic circle. He said: "These pictures were taken just before midnight, but this lovely rainbow appeared on the evening sky at 10pm"
