Oval over Boise, ID

The report, as filed

July 19, 2018, Footage of unidentified anomaly in the sky, visible for over 4 hours. From about 5:30 to 9:30pm in broad daylight to after sunset. Viewed from multiple locations several miles apart. Watched it for about 3 hours (could see it while driving at freeway speeds, and our perspective to it made it appear quite far/high) before we could get to our cameras, then filmed and photographed for about 30 min at one location, moved to another location with a high viewpoint and was still visible for about 15 minutes. We pointed it out to several people and nearly 12-15 saw it as well. Its apparent path was west mostly against wind direction from 320 at 13mph at the time. It also didn't appear to follow the rotation of the earth thus the sun's path. Appeared to hold altitude as the sun was setting, and its diameter appeared to decrease significantly from initial sighting to last sight. I was able to borrow some small low magnification binoculars and look at it after about the first hour of observing it. At any rate, the video certainly speaks for its motion shape and look. I included some comparison photos of the Moon, Jupiter, and a distant aircraft taken with the same lens and camera. We discovered another video posted from eastern Idaho of what was clearly the same object, can provide a link. Here is the link to the video we made. https://youtu.be/S-UKYgoZbxo
