I was heading out to go to a cafe to grade some papers. As I came down a long roadway I caught sight of the object and did not think much of it at first, thinking it was simply a plane or something. However, there was no movement nor sound, nor was there the flashing of lights that one would expect. I had seen a similar thing a few nights before at a different area of the neighborhood but was unable to get photos at that time (that one, too, was beginning to fade but unlike this one it had drifted out of view behind a building and I lost the chance to photograph it). Due to my missed opportunity at that time, I was more motivated to capture this one. I stopped, quickly pulled out my phone (iPhone 6) and shot a few pics and a short, 17 second, vid. I later played the vid and tried to get some screen captures from the vid (attached). As a representative here in Korea, we do see some things from time to time, but this is the first film capture I have been witness to.
