Flash of light stops above the Gallatin Range hovers and then disappears to the southI own a store and we were just closing up for the evening. We were just waking out the back door of my store looking out at the Gallatin Mountains. We saw what look like a flash of light moving east heading towards the Gallatins It was about 5:30 and was getting dark but you could still see the sky which was clear. There was no vapor trail and this was no plane. It looked like it stopped almost right on top of one of the shorter Gallatin peaks. It seemed like it was hovering there for about 30 seconds. We didn't really notice any flashing lights other than the a very slight glow it was putting off. All of a suden it took off in a southward direction from an almost standstill to the a streak of light and then was gone.((NUFORC Note: Witness does not indicate date of sighting.
