Starbase 157

From Memory Alpha, the free Star Trek reference

Starbase 157 is a Federation outpost administrated by Starfleet.

In 2366, this base picked up the final distress call from the transport Lalo. The Lalo reported encountering an unknown, cube-shaped vessel, which was later encountered and identified by the USS Enterprise-D as a Borg ship. (TNG: "The Best of Both Worlds")

This base was mentioned in the dialog of Admiral Hanson's briefing.
