You are either going to laugh or think this is really cool. I thought you would be the person to ask! What is the green object in the sky of this photo top center, a bit to the right? Is it actually something in the sky or some kind of glare from the bridge? This has never happened to me before. (Cassiopeia is looking pretty above the bridge) :-)Thanks so much in advance! :-) Patrice
