Large straight line formation from western horizon rapidly dimming out after passing overhead.

While observing Venus and Jupiter, a point of light was seen 30-45 degrees to the North of Venus rising from the horizon. At about 30 degrees it appeared to be a well-lit contrail though the sun was well below the horizon . At 45 degrees, it became evident it was a straight-line formation of 18 or more white lights spaced at irregular intervals. At 60 degrees overhead, the lights brightened to the intensity of Venus and appeared to be made up of both points and rectangular lights. The formation was longer than the space between thumb and index finger of an outstretched arm. No aircraft navigation lights were seen, and no noise was detected. After continuing eastward, the lights rapidly dimmed out. No clouds were detected in the sky. Video was captured by other witnesses several miles away and both sightings were reported to the local Sheriff’s Department.
In my opinion, given the size of the formation, the intensity of the lights, complete absence of sound, and lack of navigation lights, it is unlikely the formation was that of a commercial aircraft.
