I was sitting in my car about to go into the office I work at in a suburb of Chicago. When I noticed a bright reflection coming from an object in the sky. I noticed it moving oddly as if it was tumbling end to end but didn’t seem to be falling but flying on a relaxed heading. Didn’t seem to be moving quickly but hard to tell as I couldn’t determine size or proximity. I thought it was odd so I quickly pulled out my iPhone 7 and took a photo burst (the mode my phone happened to be on already) It then moved out of view behind some foliage.
