One continueous light with dispersed red and white lights, moving on line, not inline, SW to NE, low altitude

Long string of bright yellow light with dispersed dots of white light and one red light on left end of string as it moved across the sky from southwest to northeast. Yellow string moved as a broad front, not in a linear fashion (similar to a starlink as I understand it), along the axis of advance. Absolutely silent as it moved. Altitude estimated at 2000 to 3000 feet. Shape of the line appeared to change, as can be seen in the two pictures attached. Multiple images of the yellow line in the pictures are due to camera shake during pro-longed exposure. Unfortunately, the entire line of light is not in the pictures due to haste in grabbing the camera and taking the pictures.
