Witnessed a strange dark circle in the sky,during the daytime hoursOn, or about Nov. 2-5 2015 early in the evening 4pm -5pm I stepped out onto my back porch area. I glanced up when I saw some birds flying by, and something unusual caught my eye. By definition it appeared to be a UFO. It was flying, and it was some type of object I couldn’t identify. I ran back into the apartment and grabbed my camera. Not bothering to check the settings I put it on video mode and began recording. It appeared to be a perfect circle, and was completely black. It didn’t make any sound and was moving very slowly due north. I was able to follow the object for about 49 seconds before it slowly drifted down and disappeared behind some trees. I didn’t have any idea of what to do with the video. Feeling that it would be ridiculed I kept it to myself. When I came across this site I decided that this would be a safe place to post it. I always believed that UFO’s are real, but this is the first time I witnessed such an event. I do not claim to know exactly what it is that I saw, but it is available for scrutiny, and perhaps someone can tell me what it is. The guess work on the date and time is due to the fact that perhaps after changing the batteries, I never checked to see if the date and time were correct and just continued using the camera.
