DJI Avata 2 Captures Something Unidentifiable at Night

As I was flying around the neighborhood at 100 feet on the 4th of July, watching fireworks on the horizon, I noticed an unidentified object. It was about 200 feet in the air and moving rapidly, without making any noise, and flying too low to be a helicopter or plane. At first, I thought it might be another drone, but its speed and the distance it had already covered made me reconsider.
