Very bright circular light with a rounded dark object behind it appeared, moving S to NE, then disappeared.Circular very bright light moving quickly from a south direction towards the north-east. It was low in the sky and moving horizontally then quickly veered upwards. In back of the bright light we could see a dark rounded shape. The sky was very clear that night and we are in a very rural area with no city lights. Then the bright light vanished into nothing. There was no sound and either the object was very large or very low in the sky. There was a great deal of light movement activity in the sky afterwards for over an hour. Lights moving vertically, zigzagging, steady lights, rapidly blinking lights, disappearing lights, etc. but they were not nearly as big as the first one we saw. We are both semi-retired professionals.
