Thanks for the reply! If we are moving through our galaxy at 220 km/s how long would we have to watch one of these things to determine its precise location (assuming its close) or alternatively set a limit on its distance?

it's angular motion that you care about, so it could still be a long time. We can put some hard lower bounds on how close it could be, though. For example, it's probably not a wormhole mouth within a few ly of our solar system.
