UFO flying past Starlink train over Phoenix, Arizona

On February 18, 2021, witness was surprised to see a long line of lights at constant speed in the sky over Phoenix, Arizona, which turned out to be one of SpaceX' Starlink trains in low orbit which are small satellites to provide internet access. 


But it's not just the Starlink train that stands out it's the UFO that flies past the satellites, which is highly unusual. 

Whether the UFO is a defect satellite or in case it is indeed a UFO then could it be that the sphere has been ordered to scan the satellites for some reason? Mufon case 113721.
