I do remember someone operating a drone at night and it startled me at first, but they were there because it was a full moon out and they got some footage from the drone camera looking down at the forest and panning up dramatically to a full moon. I bring this up because the full moon is Feb. 27 (tonight), so it was still a large moon yesterday, and some photography enthusiast likely wanted the dramatic flair of getting photos with a large moon using a drone.

edit: Feb. calendar for the moon I think it's a decent hypothesis

edit2: and nobody would blame you if you got spooked seeing this in the sky if you've never knowingly seen a drone
