Long time lurker first time poster. Was at Perth T1 terminal observation deck today evening looking towards Perth Hills. Saw this black ball rise vertically while have a circular motion without being bothered by the wind. Got a certain height almost 100m( I fly a drone myself) then just disappeared. No navigation light whatsoever. This was around twilight, just after sunset. All other aircraft around had lights on. Asked the guy sitting couple of chairs next to me what it was ( he had Perth airport shirt on) and mentioned there are things he has seen that doesn't make sense, like almost "being watched". Not the best pictures but was a lot clearer to the eye. Second image is me trying to make it clear with phone editing. Any ideas? TIA 🙏
