It was the size of a football field at least, hovering over a barn on 200 North

It was a beautiful sunny day with low cloud cover. I was going home driving eastbound and I looked to the north east and saw bright lights on a sunny day facing westbound. It was the size of a football field at least. This object was hovering over a barn on 200 North in Greenfield . I then turned to the south and it went invisible in the sky, but I could still see a shadow behind it. After getting home,I went to a trail in town and by this time I was one mile south but directly across from where I saw it before. So, I looked in the sky and it came back into view again. This time I saw white and then it looked like it ?? Hanged a shape cause then I saw what looked like dark glass windows or mercury but only vertical. It just faded into the sky, went invisible.
