It's always from our PoV.
We have no idea and no way of knowing what's actually happening 600 ly. away, right now.
All our measurements are based on the light and radiation we can observe from here. We have no sensors close to it.
So if the paper is calculating supernova in couple of decades, it means the star actually went supernova 600+ years ago.

Even if we did have a satellite in orbit around Beetlejuice, its data would take just as long to reach us as the light from the star itself.

This relatively business is annoying. I suggest we just get rid of the whole thing and go back to the ether.
