Set of about 15 round white lights moving together as if connected southwest to northeast.

Several of us watched set of round white globe shaped lights move as if connected across the sky in a straight line at exact same altitude. A couple of the lights appeared almost semi transparent on the sides. No sound audible. Altitude difficult to guess but each round light about size of car light if 3 blocks away. Lights did not sparkle more of a consistant glow. Group of lights stayed in consistant row next to each other as they moved at same height across the sky. A neighbor in the area watched too..and another couple down the street were looking up watching.
