Metallic cylinder in sky, hovering still no sound or movement.

Was with my son in back yard, I looked up and noticed a very clear cylinder shaped object with looked like 5 white lights. I kept eyes on it and called my son to me, he was in a tree in yard shooting targets with bb gun. He came to me and asked "what" he could tell by tone of my voice it was something serious. I said "what's that" and pointed to object, he looked and his eyes got big, jaw dropped and said "wtf is that" I said something like I just wanted to make sure I was seeing what I was seeing. I asked him to tell me what he saw, to confirm to me what I was seeing. He said to hurry and take a picture, but didn't have phone on me and didn't want to miss at least seeing it for longer. After watching it for a minute, the object and a cloud next to it seemed to fade before our eyes not take off flying in any direction, which was also very weird. It was still light out and sky was perfectly clear and blue in area once object "faded" away, my son asked "how did it do that" like I would know. I been searching for a report of same thing before I said anything, when seen report from person in Elgin describing same thing but no lights I used that date, I know it was 1st week of Dec., was wanting to just confirm someone else's report. Being in a Chicago suburb and being very obvious in sky, I thought there would be many reports of this object. It had to be pretty big, there were a handful of planes that could be seen in both easterly and western sky and from my observation this cylinder was much bigger. Hopefully this helps someone else seeing same thing.....
