Starbase 310
From Star Trek: Theurgy Wiki
Starbase-310 was a Federation starbase administered by Starfleet. This base was located on and in orbit of Alpha Trianguli III, in the Alpha Trianguli star system. It consisted of both a small compound on the surface of the planet, near the periphery of a Federation research and dilithium mining facility, as well as an in-orbit Regula series of space station. In the early 2370s, the Federation 16th Fleet was stationed there, under the command of Alynna Nechayev.
Starbase-310 is listed as an official posting for Andrew Fisher, during the years of 2371-2377, where he was assigned as a Senior Security Officer; further details of this posting are limited.
