Was outside& noticed a red/orange glow way above Luxor, as we were watching it it started to fade& disappear b4 photo taken

I met my spouse outside after my niece ran to tell me something was in the sky, a UFO, I came out front to see there was an orange-ish red-ish craft in the sky above the Las Vegas Strip, it was staying in one place, Hoovering. Thecraft looked like it was surrounded by a fog and halo of red/orange light. It was a circular in shape. The craft faded dim fairly quick and disappeared, after less than a minute, it showed back up more towards the lower left. After the photos were taken it disappeared. We did not see it again.
