I saw it hovering on the sky during a concert. at first i thought it to be stationary, just another star. it had no blinking lights, perfectly white and round. then i realized it was moving in a straight line, and i observed it for a while. then, it quickly faded away as it moved. i observed the sky during the rest of the night, paying attention to the planes and drones flying around. all of the planes had very visible flashing, and the shape could be distinguished. during the whole time, the two drones that were recording stayed at a lower angle and had a red light on.
