While taking a photo of the sunrise this morning, I noticed a shiny disk in my picture. I waited a few minutes and took another shot. The disc was still there. I then enlarged the photo by zooming it and noticed a bright green round sphere with white dots on it. I even took another picture of the sky and the disc was still there. I waited a few minutes and took another picture and the sky had become covered in clouds so the disk was no longer visible. I immediately contacted Mufon. This occurred on December 9th at about 7 am.
