POS is X: 13.1, Y:13.0, near Goblet Southeast aetherite, overlooking the canyon at the edge of the map. Can also see it from up the hill at X: 14.1, Y: 11.7.

It's like there's a solid wall of fog surrounding the outer boundary. I'm waiting to see if it changes in the rain, but so far it's been present in all times of day and cloud cover types.
