Context: After 30minutes or so watching the sky filming this and that , I decided to watch the footage that I had captured , on my laptop . When watching the footage that I had recorded , I suddenly saw something that I had previously looked over in the garden . Upon seeing the object on my computer screen , I then realized that I had caught something rather special . My initial reaction when seeing this anomaly , was almost a sense of disbelief .
