What we see before us is an alien craft that is cloaked, however during sunset, the angle of the sun and the eyewitness were at a 90 degree angle from the UFO. When this happens, any UFO in the area will be visible from a few seconds to a few minutes. Yes a cloak is just technology...and tech always has its flaws. If you look at the photo above where I added contrast only, you will notice the front part of a disk is visible.
