Black round silent object moving slowly to northwest from southwest., no lights, no jet trail, no sound.

This evening at approximately 7:32PM, Sept. 9, ’09, I was out walking and looked up slightly to the north, and saw a small black object.  At first, I thought it was a large bird, but there was no wing movement.  No sound, no jet trail, no lights, very black.  It stayed on a steady course from the southwest to the northwest. moving very slowly.  I saw a similar object last July 3, 2008, but the sky was slightly darker, and the object was lower.  It moved very slowly, as I was able to watch it for at least ten minutes, both times. This year, there were clouds, and they appeared high and thin.  The object was black and showed up against the sky and clouds as did the object last year.  I did file a report with the National UFO Reporting Center last year as well.  The object last year, appeared to have some indentation at the top and was very black.  This time it looked more round, but the movement was exactly the same.  There is an air base (joint command) off a! bout three miles from where I live in Fort Worth, TX. in the direction the object was moving.  Last year, when I described what I had seen with a coworker he had seen the same object. He lives close to where I live.  He described the object exactly as I did, moving from the southwest to the northwest.  Interestingly, he said one of his neighbors had their cell phone and it began to make noises and light up as the object passed.  I think possibly it might be a government experiment, but it was very strange.  No triangular shape.  Just a rounder shape.  I did take a photo of the object with my cell phone, but I am not sure I captured it as it was high.  I would be glad to foreward the photo to be analyzed.  It would appear as just a black spot, small.
