Ball of light, west of city, was wiggling, observed for 20 min.I was on break at work, was looking out to the west from my position on the north west part of the city. was a cloudy evening, no stars we visible at this time, and I seen a very bright ball of light which appeared to been wiggling in the sky. The object never moved from its position as I observed it for about 20 min. When I took my next break 1hr 30 min later the object was gone. I watched the skies for the next week and never seen it again.((NUFORC Note: Sighting of Venus? Curiously, the source of the report indicates that the date of the sighting is approximate. PD))
