I was in my backyard filming the sky at about 5:30 pm just before the sunset with my smartphone for about 2 mins. I then decided to upload the film to my computer and on going through the footage I noticed a fast moving object in the sky on film. My first thought was a bird, but on going through the footage frame by frame I soon saw that it was not a bird. I decided to take a closer look at the frames by saving them as still shots. What I found was a black object that moved extremely fast in the sky changing direction as it went. I also found that as it moved, it split into two objects and then three objects that kept moving apart from each other. I also noticed that the main object changed shape, from a sphere to a cube and a square with a dome shaped top in the most closest image. As it was travelling extremely fast it looks blurred at times and even see through. A common thing with fast moving objects and as I was using my smartphone, this was the best I could do in regards to photo`s. I have provided a few still shots so that you can see the object I captured splitting into two, then three. All that has been done to the still shots, is the photo has been zoomed in on the images and slightly darkened. In one of the still shots you can see a house roof as the object moves away and then comes back for a lower closer fly by. I have also provided the part of the filming that features these objects in them. It maybe hard to see the objects at first on watching the filming due to its speed. I suggest going through it frame by frame as I have done.I posted these still photo`s on social media and someone told me that I should send them into MUFON and so here they are. Thanks for taking the time to look at these still photo`s and film for me. If you are able to get the images a lot more clearer than I could with your own stills I would be very thankful, so please feel free to do so.Kind Regards,Orion Silverstar.
