THERE'S a puzzler in our images of the week, what on earth did Rhona Walker stumble across while walking near a farm in Dunfermline? It looks like an old piece of machinery to us and no doubt our readers will be quick to let us know. We're also down on the water with very different river dwellers, the massive £6 billion-plus aircraft carriers and two little ducks. We've also got the sky at night illuminated in fiery red by the Mossmorran flare which has – for now – gone out. Thanks to our contributors, Rhona, Dennis Penny, Mike Glackin and David Bolton.
