Where Is Xur Today? (September 23-27) - Destiny 2 Exotic Items And Xur Location Guide

gamespot.com:

Like clockwork, Xur will return to the Solar System later today with a selection of Exotic and Legendary-class items that you can acquire from the Agent of the Nine. Last week saw the enigmatic arms dealer unveil not one but two sets of rare armor from his inventory, so it'll be worth checking in this week to see if he's doubling up on his goods again. We don't quite know where Xur will be just yet, but we'll update this post as soon as he arrives.

You can also check in later to see which map you'll be playing on in Trials of Osiris this weekend, as well as the Adept weapon that will be up for grabs. While you're waiting, you can also breathe easy as you won't have to slay 50 Champions to progress Season of Plunder's storyline, read up on how Lightfall's new Strand subclass introduces a cool grapple mechanic, and try out this neat Titan Solar 3.0 build that can annihilate tough enemies.

Xur is present every weekend in Destiny 2, starting with the daily reset at 10 AM PT / 1 PM ET on Friday (until Daylight Saving brings that forward by an hour in November). Bungie doesn't mark Xur's location on the in-game map, so it can be easy to miss him if you're not aware he exists. But he only comes to specific locations, of which now there are only three: the Tower Hangar area, on Nessus in Watcher's Grave, and in the Winding Cove area of the EDZ.
