White Glowing Ufo Not A Star

I've seen on more than one occation a flying object that looks like a star moving accross the sky and then it dims out and disappears. My Dad also seen this same object, it traveled really slow also? Maybe a weather balloon?

Another time my Dad and I seen a object in the sky hovering, disc shaped w/ a spinning center over the Wisconsin River. The spinning center would turn different colors, red, green, and white. Couldn't have been an airplane because it didn't make any noise and hovered in the same spot for like an hour. We went back inside the house and came back outside to see the object again but it was gone. It's hard to say the size of this object since it was miles away but would say it wasn't that big.
