I would assume that regardless of location, astronomers the world over would have noted the descent of Dalamud, and most probably felt fortunate that the second moon hitting the planet or disappearing for them overnight, didn't kill the planet.

In the MSQ, Hien tells us of an ancient writing that describes Dalamud and Azys Lla being lifted into the air by the Allagans. We know the Allagans had their hands in a lot of different pies the world over, as evidenced by their lore relating to Meracydia and the Far East. There's that entire organization that works in tandem with The Confederacy to maintain Heaven on High. They likely took note of Dalamud, but there wasn't a whole lot for them to do about it.

But anyway, even if it's only through implication, the fact that Hien knows of Dalamud means that people outside of Eorzea are aware that it was both raised by man and fell.
