Well - we have to find those probes, don't we? It took us nearly a month to find an UA. We should be better now.
If the UP is a continuation of the UA story, sort of an UA MKII, my first choice as a key system is Pleione. This idea stands or falls depending on the level of revisionism carried out by FD history department.
I'll start with the facts:
- About 50 years ago there was contact and communication with Thargoids. Soontil was discussed. Galnet source:

What used to be facts and might still be:
- About 50 years ago, Mic Turner made contact with a Thargoid ship in Pleione, on behalf of the Alliance. Communication was possible for Turner, because he had an inter species translator installed on his ship. Both Turner and the Thargoid ship were destroyed by INRA. All this happened before there was any player involvement in the Thargoid story in FFE. No branching had yet occurred.
The hypothesis would then be if UAs are monitoring the end events of the Thargoid war about 150 years ago, then the UP might monitor the events that happened 50 years ago. That would give a shell of about 40-50ly around Pleione.
The problem is of course why not use a regular UA, if you want to do the same thing over again.
Perhaps the UPs are ground probes? I don't know?
Still, all I have is Pleione.
