Bright Light that then slowly fades and disappears during Daylight

My partner and I were driving eastbound on Paseo Del Norte. We saw a bright light appear over the Sandia’s. We were perplexed because it was bigger then a plane light with nothing blinking. It wasn’t moving very fast. Yet appeared as though a bright star or flashlight. It hovered there with very minimal movement for about 30 seconds then slowly faded and disappeared. The sky was clear with blue skies right before sunset was about to start. Other airplanes were in the sky but none anywhere near that. No other lights were in the sky at this time.
