Object the color, magnitude, size of Jupiter appeared, was still and then moved at steady speed south to northMy friend and I were talking on the telephone, watching the Mars/Saturn conjunction in the west at sunset. My friend lives 300 miles to the North. I live in 'Clear 9' dark sky country and have unostructed horizons. I turned my head to the South and thought I saw Jupiter, which I though peculiar as the last time I had looked, it was obscured by the houseporch and I did not think it could have moved that far W/SW in the time we spoke. I got up and saw that Jupiter was indeed still behind the house and this object was a bright as Jupiter but was not Jupiter. Then it began to move, coming out of the area of the constellation Corvus, at a soundless, swift but steady speed. My friend saw it move at the same time and we both, still linked by phone, watched as it disappeared-or grew to faint to be seen- beneath the stars of Cygnus to the North. I have sky watched for years, took astronomy courses, have a computer generated planetarium so I know the sky.
