I saw a bright object to the northwest from northern utah county. I ran to grab my camera. When I came back up the sun had dipped below the Oquirrh's. I didn't see the bright object anymore but I saw a strange black object moving across the sky coming from that general area. Was moving too fast to get a good shot at 600 mm, but I got this screen grab from a shaky video I shot at 600mm. To me this looks like a giant clump of balloons someone let loose. Could be something different entirely from what the OP saw
