Last night in New York City, on the 26th of June 2009, nature showed one of its most amazing spectacles of the sky, the Mammatus cloud. Looking like something straight out of a science fiction movie it hovered there for enough time for all resident New Yorkers to come out on to the street and watch this amazing sight.
Have a look at these amazing pictures I have gathered from Flickr that showcase the evening. None of these are manipulated in any extreme way. In fact, some were actually taken using a mobile phone. If you click on the picture it should take you direct to the original link.
