A woman named Venetia took a photograph which seems to show a pyramid hovering in storm clouds during the night sky. It was taken in Philadelphia and it was received by MrMBB333 on YouTube. In the image, it appears as though lightning is illuminating the mysterious structure.
It should be noted that triangle or pyramid UFOs are one of the most widely reported types of UFO craft. In this particular case, if the structure is a cloud, it certainly looks a perfect 90 degree angle. The video below shows the photograph being processed by various filters to bring out the details.
