I was walking with "Mr. Green" towards a local shop in the suburbs of Trondheim. We were talking.The thing that made me notice the object, is that it "flared"/came into my field of view.I first thought the object was an afterburner on a jet, or the reflection off a polished aluminium aircraft.Then I remembered that it had no sound, and that all aircraft are painted, and not polished aluminium.The light was just sitting there in the sky, "Flaring" and changing shape. It looked just like regulare sunlight, but the sun was off to our right.I talked to "Mr. Green" who was also watching the object, and asked him what he thought it could be. he said "no idea" and told me he wondered what it could be too.We had both stopped walking at this point, and stood and watched the light.How did I loose sight of the object: It looked like it "burned out" after first flaring up.
