Starbase 245 was a Federation starbase administered by Starfleet. In 2364, the commander of this base was Don Dixon.
That year, this base was monitoring Romulan operations in Sector 0045/3195. The base commander was ordered by Commodore Anna Dixon from the Starfleet Operational Support Division that he should cease the monitoring. Monitoring duties would be resumed by remote sensor drones, a method that Fleet Ops determined was more effective. Drones would transmit data directly to the Tactical Analysis Division. The commander was ordered to acknowledge receipt of this order on subspace com net security mode 045, code 100 alpha.
At the end of that year, Data read this order and several others to investigate claims of a conspiracy among the highest members of Starfleet Command. (TNG: "Conspiracy", okudagram)
