looking west from I-80 and 60st in Omaha, Ne 1950h -2000h CST. Observed a fixed unwavering yellow globe of light at approx. 45 degrees above horizon. As I continued west the light very slowly moved south. for approx. 15 degrees. The light changed from yellow to white and appeared to diminish in size at the same position until it disappeared. Weather was slightly hazy to clear and no clouds noted. I did not see any aircraft running lights or any aircraft in the area.
