Spoiler warning: Plot and/or ending details follow.
The system was fairly close to the Tarsus star system.
In orbit of Epsilon Sorona were a number of worlds. In the 2240s this included a Federation colony on the second planet Epsilon Sorona II. A disaster of some sort took place on that world prior to mid-2246, and the colonists there were relocated by the Federation to Tarsus IV. (DSC novel: Drastic Measures)
