Stellar cartography
The Seginus system was visible from Earth in the constellation Boötes. It was approximately 86 light years from Sol.
In the 2150s, this system's position was labeled on an United Earth star chart which was displayed in several crew and guest quarters aboard the Enterprise. (Star Trek: Enterprise, set decoration)
In 3195, the position of "(Gamma Bootis)" was labeled on a Federation star chart which was used in Starfleet Academy's Temporal Mechanics classroom. (SA: "Beta Test")
Later that year, this system's position was labeled on a Federation star chart which was displayed on the bridge of the USS Athena. (SA: "Come, Let's Away")
In 3196, during the Omega-47 crisis, the location of "Seginus (Gamma Bootis)" was depicted on star charts and readouts used across several locations on the USS Athena to locate, monitor, and respond to the Omega-47 mines laid by the Venari Ral. (SA: "300th Night", "Rubincon")
