Blue Hour Sky With No Clouds

Brief

In this contest I would like to see your photos that have been taken during blue hour, where the orange glow of post-sunset meets the rich blue skies of impending night. Images can show landscapes or cityscapes but please ensure at least one third of your photo shows a cloudless sky during blue hour. In the interests of fairness to other photographers please ensure you stick to the brief. I look forward to seeing your images.
