The name isn't random! It's common in astronomy to encode the targets position in the name in sexagesimal units. It's useful because you can read the name and immediately know where it is on the sky. In this case, J1832-0911 means a right ascension of 18h(hours) 32m(minutes) and a declination of -9°(degrees)11'(arcminutes). Using this, you could quickly work out whether it's visible from your location.
