I was travelling east on the m4 motorway between cardiff and newport in south wales on sunday 5 november 2017 at approximately 4.05 pm. in the sky to my left was a white object which did not appear to be moving. i took 2 photos on my iphone 7 but they are not very clear. once home, i enlarged the images and saw that the object was definitely nothing i recognised, appearing as 4 vertical rectangles side by side. had i been alone i would have pulled off the motorway to view the object further, but unfortunately this wasn’t the case.
