Anyone else notice the weird lights over Lake Michigan last Thursday around 11pm?

Bit of an odd one to ask here since I'm based in Glasgow so obviously I wasn't there, but a mate sent me a video last Friday morning saying he filmed something over the lake the night before around that time. The footage is pretty shaky but you can make out maybe 3 or 4 lights in a loose triangular arrangement, not moving like aircraft would. They just sort of hang there and then two of them seem to drift apart slowly.

What I'm trying to work out is whether anyone else actually witnessed this in person, because video alone is hard to analyse without knowing the broader context of what was visible that night. Were the lights coloured or just white? Any sound? The reason I ask about sound specifically is that my mate says he heard nothing at all, which rules out a few conventional explanations straight away.

If multiple independent witnesses clocked the same thing from different positions around the lake that would be genuinely significant for ruling out a single light source or reflection.

Not my area really, I'm more of a SHC man myself. But I'd say get your mate to post the video here if he's willing - without footage this sort of thing tends to go nowhere fast and people just argue in circles about what it could have been.

What direction was he facing when he filmed it? That'd help narrow things down a bit.

Would love to see that footage - living in Roswell you'd think I've seen everything but Lake Michigan reports have been popping up more than people realise lately. What time zone was your mate recording in, and did the lights move in formation or independently? Those two details tend to separate the interesting cases from the mundane ones pretty quickly in my experience.
