In the photo at the top you will notice this UFO has a jellyfish appearance, which is a common type of UFO. It glows like it has its own light source and it also has a shape of a star with five points. Also note the hole it made in the cloud around it. UFOs are known to make holes in clouds (O'hare UFO sighting proves this point), just as this one did. In the photos with the people in it at the bottom, we see a lot of eyewitnesses looking up at the sky at this object. It was noticed by a lot of people that day. They are trying to be notices but doing it gently to not cause anyone fear. SCW
