I first noticed the 2 light objects while walking at approx 9:00 pm in Trabuco Canyon Ca. I called my wife who was driving to store, she also obs the objects. When i returned to my home the light objects moved slightly n/w from the originl sighting. the span was over 30 minutes. The spacing between the 2 lights did not change. Still brighter on bottom and smaller on top at eleven oclock. Over the the next 30 mins I lost sight due to elevation and home roofs.
