I am a guide and was around a campfire in the very dark desert. The moon had not come up at this time over the La Sals. Several of my clients watched this event. We suspect it was space debris of some sort. Awfully large for meteor or asteroid 'shower' particle. We figured it hit someplace in Moab unless it all burned out!
