Semi-transparent white ball sighted in Queen Creek ,AZI sighted a white semi-transparent round ball coming over my house from the Northwest traveling Southeast approximately 400 feet in the air. It covered approximately 2 miles in 40 to 45 seconds , just skimming the top of the San Tan Foothills. The weather that day was 75 and Sunny no clouds at all in the sky, winds were 5 mph. There was no noise coming from the ball (object) and never changed altitude the entire time it was in sight. If I had to estimate the size of the object I would say it was as big as a king sized bed. Again ,it was translucent or semi-transparent white in color with no metallic features at all. I'm just hoping it was reported by someone else as well.
