Some long exposures just after sunset. The darker two are five-second exposures, and the lighter two are 15-second exposures. The bright streak in 5218 is a moving helicopter. Were it not for that interesting feature I would have deleted it for its camera shake. 5224 in contrast is quite still. The sky appears as bright as day, but much brighter in the west than in the east. The clouds are sodium orange and smeared by their own motion across the sky, and the stars are out.
