...folks are saying there were no NOTAMS for the area.

Yeah, well, that just goes to show ya not ta always believe what "folks are saying." HERE'S your supposedly-nonexistent NOTAM, for the LA area. Note especially the effective dates, and how they nicely bracket the time this "mysterious object" appeared in the sky: 14:30 NOV 8 until 19:30 NOV 10.

Ok,
That settles that question...then if a NOTAM was filed....that leaves US entities. Somebody just began a private space program...look for some consortium of Silicon Valley billionaires to be high-fiving each other real soon.
