In 2269, the USS Potemkin was scheduled to rendezvous with the USS Enterprise in the Beta Aurigae system to conduct gravitational studies of the effects of the two major binary stars of Beta Aurigae. Before they could meet up at the system, the Enterprise received a distress call from Camus II causing the mission with the Potemkin to be delayed. (TOS: "Turnabout Intruder")
"The Explored Galaxy"
"The Explored Galaxy" was a map of charted space in the Alpha Quadrant. The Beta Aurigae system was located west of the Tholian Assembly. The Assembly was identified in DS9: "Call to Arms" as being located in the Alpha Quadrant. This chart, first seen chronologically in Star Trek VI: The Undiscovered Country, was also seen in several Star Trek: The Next Generation and Star Trek: Deep Space Nine episodes set in the 24th century, from the year 2364 to 2370. These were TNG: "Conspiracy", "The Measure Of A Man", "The Emissary", "The Mind's Eye", "The Game", and DS9: "In the Hands of the Prophets", "Cardassians".
