I'm in Eastpointe and one just passed probably an hour ago heading east. Other than the navigator lights, I couldn't make out the sort of helicopter it was or what colors it was shaded [[especially since I was looking from inside a lit room). It was also flying pretty low.

In the daytime, I've seen Coast Guard helicopters fly at similar heights but there were always going north-south. In the end, I assumed this recent helicopter to be another Coast Guard one just flying in a different direction. The points of the navigation lights seem to fit that of a Coast Guard heli.
