Anybody know what this is?

Filmed on May 31, 2024. Spotted south of Las Vegas. Moving in a southeast direction. Was visible for about one minute before disappearing, and leaving behind a faint glow in the sky that dissipated. There were absolutely no clouds in the sky. Has a small tail. The star in the background of the first video (above and to the left of the UFO) is Arcturus (has an apparent visual magnitude of -0.05) from the Boötes Constellation. The moon phase was a Waning Crescent this day with an illumination of 38.87%. When I first spotted this object I was looking 210° (SW) and when I last spotted this object (when it disappeared) it was at about 130° (SE).
