If I'm not mistaken this is the blue kachina anons were referring to.
We know it's not a comet and we know it's local to our realm, but what exactly is it? If it's the blue kachina, then it's a "star" but then what is a star and why is this one different? I've heard some theories about stars being us in some way, I would guess it's our light-bodies, our binary LED projection of our energetic dream realities. Kachina means spirit in Hopi (I unfortunately have not looked much into Hopi myth, but I will) - so it makes sense it's a powerful, non-local spirit or light-body that's come to our realm to deliver a message.
From a technological viewpoint, stars would be the computer-code, purely LED lights in the sky containing information about all of us, most likely connected to the functioning of the Halls of Amenti. The Blue kachina is another piece of computer-code, a blue LED light that turns on based on certain parameters.
Regardless it serves the same purpose - to tell us that most likely a sky event or THE SKY EVENT is coming. Or maybe it's something else entirely kek.
