I saw this in the northern Chicago suburbs toward Lake Michigan. Two objects and one of them super bright. I thought these were planes at first when I went to pick up a few groceries. When I came back out they were still there (about 20 minutes or so).

Sometimes the smaller, flickering light would fade out, fade back in, move above the brighter object, then disappear and reappear on the side... but it would all happen slowly over the course of a few minutes at a time. The bigger, brighter object seemed stationary the whole time.

I took a few videos and stitched them together. Not great, I wanted to take a longer one but felt weird clearly recording video with other shoppers nearby and no one else seemed to notice.

Curious if anyone else in the area may have seen it. Or maybe someone knows if it's just a couple of helicopters or something.
