Lights in the Sky

I was aimlessly flying the Expedition over Brigadoon when I saw two mysterious lights in the sky. I moved closer to investigate.

The lights were in the southeastern portion of Brigadoon, near the Hummingbird Ballroom and Miss Vandeverre's emporium, at about 145 meters. As the photo below shows, the cavorite mountain of Morgaine can be seen to the south behind the lights.


I am at a loss to explain the lights. I welcome guesses - educated or otherwise.
