UFO Sighting in St. George, Utah on 2017-03-08 00:00:00 – Taking pictures of chemtrails, did not notice orb untili i reviewed them later

From the pictures you can see it is a white energy ball, it ascended and descended, seemed to be emitting it’s own light, wondering if anyone has seen this before? would love to get some feedback. also i was taking pictures of chem trails in southern utah where there is a lot of unusual activity.
