I never knew what to make of this, but I did observe once that 100%-normie and NASA fanboy youtuber "Smarter Every Day" once incidentally noticed something similar to Crow777's "lunar wave" while trying to get a particular landscape photo with a large moon in it. He asked his audience "what's that line on the moon?" that he captured in a still image, because he couldn't figure it out. I think he made a reddit post about it or something. I looked to see if he ever resolved it but didn't find any obvious update. This was a while ago now, so maybe he mentioned it again since. I haven't watched a video of his in a couple of years.
